Different shapes and their names

Different Shape Names (with Useful List, Types) • 7ESL

Are you looking for different shape names in English? Here you will find a list of shapes with different types and useful example sentences. If you work in a business that requires the use of mathematics, for example then it would be very important that you are aware of the English names for shapes.

However, this may not be the only reason that you need to learn this information. When taking part in day-to-day conversations, you will need to learn the shape names in order to describe something or be able to understand what someone is talking about, for example, if a person tells you about ‘the square plate.’ Here, you can learn shape names and further expand your vocabulary.

Shapes

What Are Shapes?

Shapes are geometric figures, or the pattern an outline falls into. Shapes are often drawn (whether by ink, pencil, or digitally), but they occur in life, also. Frequently, people picture 2D (two-dimensional, or flat) images when they hear the word “shapes,” so most of the objects listed in this lesson will be 2D shapes, but some will be 3D as well.

Different Types of Shapes

There are many, many different types of shapes, and there are names for basically all of them. The following list focuses on more common shapes that you’re more likely to encounter or to need or want to know the name of.

Shape names with pictures

Two-Dimensional (Flat) Shapes

Circle: A circle is an equally round shape. Picture the lid of a jar, flat, from above. That is a circle. The wheels on a car are circular, as well. So are the holes in most lined paper and notebooks.
Oval: An oval is basically a circle that’s been a little squished. The cups of over-the-ear headphones are generally referred to as oval. So is the profile of an egg. Some make a distinction between circles that have been squished in the middle versus circles that have been squished at the top, the former being called an ellipse, but common usage treats both as ovals.

Rectangle: A rectangle is a shape with four sides, made up of two sets of parallel lines, with four right angles (90 degree angles; picture a capital L). It doesn’t matter whether the sets of sides are the same length. Picture a plain piece of printing paper. This is a rectangle, with one set of sides (generally the top and bottom) shorter than the other set of sides (generally the left and right).
Square: A square is a very specific type of rectangle, one with four equal sides. Some boxes have a square footprint. Origami paper is square.
Triangle: A triangle is a shape with three straight sides. These sides can be any length, with any degree of angle, as long as the three sides are joined at their ends. Many warning signs are triangular. A slice of a round pizza is mostly triangular (the crust is a little too rounded to be perfect).
Pentagon: A pentagon is a shape with five sides. A basic drawing of a house, with two lines for the roof, a line for each side, and a line for the bottom is generally a pentagon.

Shapes with more sides are generally named based on how many sides they have. A hexagon has six sides, heptagon has seven, and an octagon has eight.

Three-Dimensional Shapes

Three-dimensional shapes are ones that aren’t just flat on paper, but also take up room vertically. Only a few are really commonly named.

Sphere: A sphere is a 3D circle, like a ball.
Cube: A cube is a 3D square, like a box.
Pyramid: A pyramid is a 3D triangle. The giant structures in Egypt are pyramids, as is the Luxor in Las Vegas.

Shape Names

It’s important to build a good vocabulary, in any language. The more words you know and understand, the better you can communicate. Even if you don’t use the words often, understanding them allows you to follow along with a conversation, even if it ventures a little outside of your comfort zone. This lesson is specifically focused on different types of shapes.

Geometric shapes and their names

Here you and your child can learn geometric shapes and their names through fun picture activities. But training will be most effective if you add various samples of geometric shapes to the printed task. For this purpose, objects such as balls, pyramids, cubes, inflated balloons (round and oval), tea mugs (standard, in the form of a cylinder), oranges, books, balls of thread, square cookies and much more - everything what your fantasy tells you.

All of the above items will help the child understand what a three-dimensional geometric figure means. Flat figures can be prepared by cutting out the desired geometric shapes from paper, pre-painting them in different colors.

The more different materials you prepare for the lesson, the more interesting it will be for the child to learn new concepts for him.

You may also like our online math simulator for grade 1 "Geometric shapes":

Geometric shapes grade 1 - Online simulator

Online math simulator "Geometric Shapes Grade 1" will help first-graders practice their ability to distinguish between basic geometric shapes: square, circle, oval, rectangle and triangle.

So that the child can easily and naturally remember geometric shapes and their names, first download the picture with the task in the attachments at the bottom of the page, print it out on a color printer and put it on the table along with colored pencils. Also, by this time, you should already have prepared various items that we listed earlier.

Stage 1. First, let the child complete the tasks on the printed sheet - say the names of the figures aloud and color all the pictures.
Stage 2. It is necessary to clearly show the child the differences between three-dimensional figures and flat ones. To do this, lay out all sample objects (both three-dimensional and cut out of paper) and move away from the table with the child at such a distance from which all three-dimensional figures are clearly visible, but all flat samples are lost from sight. Draw your child's attention to this fact. Let him experiment by moving closer and further away from the table, telling you about his observations.
Stage 3. Further, the lesson must be turned into a kind of game. Ask the child to carefully look around him and find objects that have the shape of any geometric shapes. For example, a TV is a rectangle, a clock is a circle, etc. On each found figure - loudly clap your hands to add enthusiasm to the game.
Stage 4. Conduct research and observational work with those sample materials that you have prepared for the lesson. For example, put a book and a flat rectangle of paper on the table. Invite the child to feel them, look at them from different angles and tell you their observations. In the same way, you can explore an orange and a paper circle, a children's pyramid and a paper triangle, a cube and a paper square, an oval-shaped balloon and an oval cut out of paper. You can add to the list of items yourself.
Stage 5. Place various three-dimensional samples in an opaque bag and ask the child to feel a square object, then a round object, then a rectangular one, and so on.
Stage 6. Lay out on the table in front of the child several different items from those that are involved in the lesson. Then have the child turn away for a few seconds while you hide one of the objects. Turning to the table, the child should name the hidden object and its geometric shape.

Basic geometric shapes

Each of us, both adults and children, noticed how many geometric shapes exist around us. We meet them everywhere, in all the objects around us. Where are geometric shapes found in our lives?

Where are geometric shapes found in our lives?

Each of us - both an adult and a child - noticed how many geometric shapes exist around us. We meet them everywhere, in all the objects around us.

People have long been interested in the variety of geometric shapes. Even for primitive people, the shape of the objects surrounding them played an important role. Mastering the world, people got acquainted with the simplest geometric shapes. At first they made tools of relatively regular shape, then they learned how to improve them. At that time, of course, there were no special names for geometric shapes. They were invented much later. When people began to build houses, they had to understand even more deeply the features of different figures in order to understand what shape walls and roofs should be given, what shape logs or stone blocks should be. Without knowing it, a person was constantly studying figures: women, making clothes, hunters - spearheads or boomerangs of complex shape, fishermen, making such bone hooks so that the fish would not fall off them.

One cannot live without this knowledge in the modern world.

Where are geometric shapes found in our lives?

Perhaps someone thinks that the various lines of the figure are "found" only in the books of learned mathematicians. However, if you look around, it becomes clear that many objects have a shape similar to the main geometric shapes. We just don't always notice it. Many wonderful geometric shapes are found in the nature around us. The field has the shape of a rectangle, the river has a curved line, the lake has a circle, a salt crystal has the shape of a cube, an ordinary pea, a dew drop has the shape of a ball. Beautiful and varied polyhedrons - crystals of rock crystal. But in everyday life, the basic geometric shapes are also everywhere. These are buildings, structures, transport, apartment interiors, even dishes and clothing. For example, a woman's skirt is a trapeze, a plate is a circle, a house is a square and a triangle, and a cylinder is in a pipe.

Knowing all the figures, their types, names and properties is very important. Systematizes knowledge about geometric shapes and studies their properties of mathematical science - geometry. This science is very important, its application is simply priceless at all times and regardless of profession. Neither a worker, nor an engineer, nor an architect, nor an artist can do without knowledge of geometry. And it is very important to start mastering this science at an early age.

The iSmart educational platform will be a great help to your child. The main types of geometric shapes, their properties, tasks for finding the area of figures and much more are on the platform in the "Mathematics" section. Here are collected several thousand tasks for the development of these topics, which are not repeated during repeated development. Being engaged in, primary school students will thoroughly understand the basics of geometry. This will give them a good base in the subject for their middle and high school studies. In addition, interactive tasks are colorful, interesting, and exciting.

So,

The simplest types of shapes

The two basic shapes are a point and a line. The accumulation of points and lines forms various geometric shapes. Each of them is individual, differs in its parameters, their forms are very diverse. Figures are simple and complex, flat and voluminous.

Point

Point is the smallest, but at the same time the most important object in geometry. This is the smallest geometric figure, but it is it that is necessary for constructing other figures on the plane and is the basis for all other figures. It does not contain such properties as length, height, volume, area, does not have measuring features and characteristics. It only matters where it is located. The point is indicated by a capital letter of the Latin alphabet or a number. For example, A, B, C or 1, 2, 3.

Any more complex geometric figure is a set of points , which have a certain property that is characteristic only for this figure.

The simplest figures are a ray and a segment.

^{A ray} ^{is a part of a line that has a starting point but no end. This is a one way extension.}
^Segment ^{is a component of a straight line bounded by two points. It has a beginning and an end, so it is measured. The length of a line can be determined by measuring the distance between its ends.}

Line

A line is formed from a set of dots arranged one after another and connected to each other. Lines are closed and open, straight and curved, as well as broken.

^Closed ^{- when the start and end parts of the direction are located at the same point. An inverse version is obtained from an open line.}
^Open ^{- when the start and end of the line are not connected.}
^Straight ^{continuous line unchanged.}
^Curve ^{is not a straight line.}
^Polyline ^{- when segments are not connected at an angle of 180 degrees.}

An infinite number of lines can be drawn through one point, but only one straight line and many curves can be drawn through two points.

Basic geometric shapes

Connected points form lines, and interconnected lines form basic geometric shapes on a plane.

Geometric figures are flat or two-dimensional (2D) and three-dimensional or three-dimensional (3D). They are bounded by the closed surface of their outer boundary.

If all points of a figure are in the same plane, then it is flat. Flat figures that everyone knows: point, square, rectangle, triangle, circle, semicircle, circle, oval, rhombus, trapezoid.

And if all the points of a geometric figure are not in the same plane, then it is voluminous. These include a ball, cone, cylinder, sphere, pyramid, etc.

Let's analyze flat figures.

Triangle

Triangle is a figure that is formed when three line segments connect three points that do not lie on the same line. These three points are called vertices, and the segments are called sides.

There are three kinds of triangles:

^Rectangular ^{- when one angle is right, the other two are less than 90 degrees.}
^Acute ^{- when the degree of its angles is greater than 0 but less than 90 degrees.}
^Obtuse ^{- when one angle is obtuse, that is, more than 90 degrees, and the other two are acute.}

Triangles have the following properties:

^{in a triangle opposite the larger angle lies the larger side and vice versa;}
^{the sum of the angles of a triangle is always 180 degrees;}
^{all angles of an equilateral triangle are 60 degrees;}
^{in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the legs (but this is already studied in high school).}

The vertices of triangles are indicated by capital letters of the Latin alphabet: A, B, C, etc.

Examples of triangles:

from center distance.

Circle

The part of the plane inside the circle is called circle . That is, the circle is the boundary of the circle. And the distance from the center of the circle to any point on it is called the radius. The diameter of a circle is a line segment that connects two points on a circle and passes through its center. The diameter of a circle is equal to two of its radii.

‍

Rectangle

‍

Rectangle is a figure consisting of four sides and four right angles, which has:

^{opposite sides are equal;}
^{the diagonals are equal and bisect at the point of intersection;}
^{a rectangle can be circumscribed by a circle centered at the point of intersection of its diagonals and with a radius equal to half of the diagonals.}

‍

Square

Square is the same rectangle with:

^{all sides are equal;}
^{all angles are equal and equal to 90 degrees;}
^{the diagonals are equal and perpendicular;}
^{the centers of the inscribed and circumscribed circles coincide and are located at the point of intersection of its diagonals.}

‍

Trapezoid

A quadrilateral with two sides parallel and two not is called a trapezoid . If the sum of the lengths of the bases of a trapezoid is equal to the sum of the lengths of the sides, then a circle can be inscribed in it.

‍

Parallelogram and rhombus

Parallelogram is a quadrilateral whose opposite sides are pairwise parallel.

Rhombus is a parallelogram with equal sides.

A parallelogram has the following properties:

^{opposite sides and angles are equal;}
^{the sum of any two adjacent angles is equal to 180 degrees;}
^{the diagonals intersect and the intersection point is bisected;}
^{each diagonal divides the figure into two equal triangles.}

Basic quantities and their formulas

All geometric figures have their own characteristics and their own value. The most common are such quantities as area and perimeter. They are used in everyday life, in construction and in other areas. For example, during renovation or new construction, the amount of materials needed and the scope of work cannot be determined without calculating the area and perimeter in advance.

Perimeter

Perimeter is a closed boundary of a flat geometric figure that separates its inner area from the outer one. Any closed geometric figure has a perimeter:

In the figure, the perimeters are marked with a red line. The perimeter of a circle is often called the length.

The perimeter is measured in units of length: mm, cm, dm, m, km.

Designated by capital Latin P .

Area

Area is the part of the plane occupied by a closed flat geometric figure, that is, that part of the plane that is inside the perimeter. It is she who gives us basic information about its size. Any flat closed geometric figure has a certain area.

‍

In the figure, the areas of the figures are colored in different colors.

To measure the area of a figure means to find how many times another figure is placed in a given figure, taken as a unit of measurement. Area is measured in square units of length. Area units include: mm ², cm ², m ², km ², etc. S (square) - a sign of the area.

Calculate perimeter and area

Perimeter is the length of a closed contour of a geometric figure. You can, of course, measure the length of all sides with a ruler and add them. But it is better to use special formulas for calculating the perimeter, this will greatly simplify the task.

^{Square: perimeter = 4 * side.}
^{Triangle: perimeter = side 1 + side 2 + side 3.}
^{Irregular polygon: perimeter = sum of all polygon sides.}
^{Circle: circumference = 2 * π * radius = π * diameter (where π is pi (a constant approximately equal to 3. 14), radius is the length of the segment connecting the center of the circle and any point lying on this circle , the diameter is the length of the segment passing through the center of the circle and connecting any two points lying on this circle).}

To calculate the area of the figure, the corresponding formula is also required. Different formulas apply to different figures. To calculate the area of standard geometric shapes, you can use the following formulas:

^{Parallelogram: area = base * height}
^{Square: area = side 1 * side 2}
^{Triangle: area = ½ * base * height radius is the length of the line segment connecting the center of the circle and any point lying on this circle.The square of the radius is the value of the radius multiplied by itself).}

So, we have listed the main and most common geometric shapes and their properties. The iSmart educational platform will help your child learn basic geometric shapes, their types, names and properties through fun activities.
