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.

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

Shapes- Definition, Types, List, Examples

LearnPracticeDownload

The shape can be defined as the boundary or outline of an object. It is the surface we see and does not depend on the size or the color of the object. Everything around us has a different shape, such as the square, rectangle, or three-dimensional sphere. Have you seen the model of the Earth called the globe? What is the shape of this globe? Have you noticed the shape of a pizza? It is round in shape. If we cut out a slice from the pizza, the slice gets a triangular shape. Let us learn all about shapes, types of shapes, and geometric shapes.

What are Shapes?

Shapes define the boundary of an object and can be differentiated in many ways based on their properties. These shapes are closed by a boundary which is made by combining the curves, points, and line segments. Each shape has a name depending upon the structure. Few shapes are circle, square, rectangle, triangle, and so on.

Types of Shapes

Shapes can be classified into various categories. Before classifying shapes further in separate structures the basis of each shape depends on the following classification:

• Open Shapes: Open shapes are not continuous and are made up of line segments or curves which do not meet. Letter C is an example of an open shape.
• Closed Shapes: Closed shapes can be traced without any break. They start and end in the same place. Letter D is an example of a closed shape.

Further, each shape is classified on the basis of dimensions it has. In this section, we will discuss the two major types of shapes:

• Two-dimensional (2D): 2D shapes, as the name suggests, have only two of these measurements, i.e., length and breadth.
• Three-dimensional (3D) shapes: 3D shapes have a length, a width, and a height. You can learn more about it here.

A square is a 2D shape, whereas, a cube is a 3D shape.

List of Shapes

We know that shapes are made of straight lines or curved lines and they can be open or closed. Lines are defined as a collection of points. In other words, many points are put together to form a line. They may form a straight line or a curved line. Shapes are closed shapes that are created by joining lines together. Closed shapes made of four straight lines are called quadrilateral shapes. Given Below is the list of shapes with real-world examples.

• Circle: A circle is a closed shape. It is categorized as a two-dimensional geometric shape that is round in structure. It does not have any lines or corners. For example, the wheel of a vehicle, pizza base, dartboard.
• Oval: An oval is an elongated shape slightly similar to a circle. It has no straight lines or corners. For example, the number zero (0).
• Square: A square is a closed 2-D shape that is formed by four sides. The length of each side is equal in measurement. For example, a chessboard and a carrom board.
• Triangle: A triangle is a shape with three sides and is categorized as a two-dimensional geometric shape. For example, the shape of tangy nachos, one slice of cheese burst pizza.
• Rectangle: A rectangle has four sides. It is a two-dimensional geometric shape in which the length of the opposite sides is equal. For example, laptop screen, touch screen mobile phones etc.
• Polygons: A polygon is a closed two-dimensional figure with three or more straight lines. For example, windows, doors.
• Cube: A cube is a closed three-dimensional geometric shape. It is made up of six squares. It has six faces. For example, a Rubik's cube, a ludo dice, an ice cube.
• Cuboid: A cuboid is another three-dimensional shape that is formed using rectangles. For example, a duster, a book, a pencil box.
• Sphere: A sphere is a solid shape that is similar to a ball. It is a closed three-dimensional shape formed using a circular base. For example, football, basketball, etc.
• Cylinder: A cylinder is a solid shape that has two flat ends of circular formation. It is a three-dimensional figure which is formed by folding a rectangle. For example, coldrink cans, pool noodles, water bottles.
• Cone: A cone is a solid three-dimensional geometric shape with a flat base. The base is circular in shape. It has a pointed edge at the top called the apex. For example, ice-cream cone, clown hat, etc.

Are the figures not flat?

Non-planar forms differ from planar forms in that they cannot be represented by only one plane, that is, they have more than one plane. They are known as geometric or three-dimensional solids. See example below: Non-planar shapes or solids have vertices, faces, and edges.

What flat figures form a spatial figure?

Plane and spatial figures

• CIRCLE, very round;
• TRIANGLE - a geometric figure with three sides.

How to determine the type of female figure?

As Hillary Kerr rightly said, fashion trends are guided by standards that are rarely found in real life. Therefore, you should not be upset by an unfavorable comparison with photo models, it is better, having studied the features of your figure, to determine its type and, taking into account individual characteristics, choose a wardrobe.

Calculation technique by fashion expert Bradley Bayou

Creating a calculation technique to determine body types is a major breakthrough in revealing the secrets of beauty and fashion. Bradley Bayou in The Science of Sexuality lists 48 female body types. If we take his arguments into service, it turns out that the main thing in appearance is not the number of kilograms, but their distribution.

Consider the four basic body types according to the formulas given by Bradley Bayou. Each woman in relation to these data will be able to determine her type of figure, and, guided by the advice of experts, determine the silhouette that is suitable for herself.

Measurement of parameters: step one

To determine the body type, we need a centimeter tape, a piece of paper, a pencil and an assistant.

Shoulder width

Shoulder width is measured from the extreme point on the left shoulder to the same point on the right. The assistant stands behind and stretches the tape from the left to the right shoulder. The tape is positioned horizontally without undue stress. The obtained values ​​are recorded.

Waist circumference

To determine the waist size, it is convenient to tie a thin belt around the narrowest point above the navel. When we have marked it in this way, we stretch the centimeter tape around the belt. We write down the numbers.

Chest circumference

The volume is measured by placing the tape on the most convex parts of the chest and back. The tape is located freely, the chest is not squeezed. We write the data.

Hip circumference

Tape runs from the bottom of the thigh, along the largest bulge of the abdomen and wraps around the protruding parts of the buttocks, back to the thigh. We fix the numbers.

Calculation of body type: step two

The figures obtained will help in determining the body type. There are figures in which certain parts of the body are excessively or less developed than others. For example, prominent or vice versa sunken chest, narrow or wide shoulders. In this case, in order to get the correct conclusions when making calculations, it is recommended to swap these values.

If the violation of the proportions between the width of the shoulders and the girth of the chest leads to the fact that the physique simultaneously falls under two definitions: a pear and an hourglass, then they try on clothing models for the first and second types, choosing the one that best suits you.

Now consider the four main types of figure. From the description, try to determine which category your body belongs to, and then test your assumptions using the Bayou equations.

Inverted Triangle

Broad shoulders, large breasts - narrow hips: a figure that schematically resembles and is designated as an inverted triangle.

Mathematics will help you to finally establish your opinion that your figure belongs to this type.
Example: shoulder width - 91.5 cm, hip circumference - 87 cm = inverted triangle.

Clothing Tips

An inverted triangle silhouette should visually balance the top and bottom. Fitted items with flared bottoms are the main style for women with this body shape.

Rectangle

Shoulders, bust, hips approximately equal. The waist is expressed weakly, indistinctly.
Formula: waist > shoulder width/bust by 25%.
The difference between the size of the shoulders, chest, hips within 5%.

To derive our own formula, we take the largest value: the width of the shoulders, denote it as X, denote the other dimensions as Y, Z.

Multiply X by 0.95. If the resulting product is less than Y and Z, the ratio between your parameters corresponds to 5%.

Example: shoulder width 91.5 cm, waist circumference 68 cm = rectangle.

Clothing tips

Skirts with frills, bows, pockets. Things that optically enlarge the lower part of the body.

Triangle (pear)

Hips wider than shoulders, well defined waist.
The difference between hips, shoulders and bust is more than 5%.
Shoulders - 91.5 cm, hips not less than 96 cm = triangle (pear).
