Pin

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.

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.

Shapes – Definition with Examples

What are Shapes?

In geometry, a shape can be defined as the form of an object or its outline, outer boundary or outer surface.

Everything we see in the world around us has a shape. We can find different basic shapes such as the two-dimensional square, rectangle, and oval or the three-dimensional rectangular prism, cylinder, and sphere in the objects we see around us. These geometric shapes appear in objects we see as credit cards, bills and coins, finger rings, photo frames, dart boards, huts, windows, magician’s wands, tall buildings, flower pots, toy trains, and balloons.

Shapes can be classified into open and closed shapes.

Closed geometric shapes can further be put into two broad categories, namely two-dimensional and three-dimensional shapes.

Here’s a list of 2-D or two-dimensional shapes with their names and pictures:

Here’s a list of 3-D or three-dimensional shapes with their names and pictures:

The color, overall size, and orientation called the non-defining attributes of a two-dimensional or three-dimensional shape do not define or affect the shape in any way. These attributes can change without any effect on the shape. 

On the other hand, defining attributes such as the number of sides (parallel or non-parallel, straight or curved), vertices, edges, and faces of a shape, whether the shape is open or closed, and the angle measures determine the shape of a two-dimensional or three-dimensional object. Any change in these defining attributes will change the shape.

Cognition of the world - types, levels and forms

The philosopher Socrates said: "I know that I know nothing." And, most likely, this phrase is familiar to modern schoolchildren firsthand. 🤓 Let's see what are the main types of cognition that help us interact with the world.

Definition of knowledge

What is knowledge ? This is a set of processes and methods through which you can gain knowledge about the world around you.

This is a broad concept that covers both the natural desire to find a logical explanation for the processes taking place around, and artificially created methods for obtaining and accumulating knowledge.

The desire to explain every phenomenon of the surrounding world is the main factor in the emergence and development of human civilization.

Structure of knowledge:

1. Subject - one who performs actions that are aimed at obtaining knowledge. For example, you are reading this material to find out the types of cognition and their characteristics. It turns out that you are the subject of cognitive activity.

2. Object is what the subject's activity is aimed at. For example, now the object of your cognitive activity is the concept of cognition and its types.

3. Motives - why we do something. There are two types of motives:

   • Practical motives push to possess knowledge in order to use it to improve the quality of life (studying at the institute gives a profession that feeds).
   • Theoretical motives are based on getting pleasure from the very process of cognition (read a book and add to the library of your knowledge).

4. The purpose of cognitive activity is to obtain true, reliable knowledge about the world, understanding how reality actually works.

5. The result of is the very knowledge of an object or phenomenon. Sometimes the result is obtained unconsciously, for example, if a child plays with a clay mug and breaks it, he will immediately understand that the clay is fragile and will handle the dishes more carefully.

Now we will find out what methods of cognition exist, and then we will move on to forms.

Methods of cognition

All methods of cognition can be divided into two large groups: empirical and theoretical.

Empirical methods - the identification of objective facts, as a rule, from their obvious connections.

Theoretical methods are the identification of fundamental laws, the detection of hidden manifestations behind visible ones, internal connections and relationships.

Empirical methods:

• Observation - the researcher studies the object in its natural environment without affecting the ongoing processes.

• Measurement - the researcher obtains the numerical characteristics of the object through which he observes, and compares its properties with exemplary values.

• Experiment - the researcher deliberately creates special conditions and then studies the object that he places in them.

• Classification - the researcher combines the studied objects into groups according to the same properties.

• Systematization - the researcher combines the accumulated knowledge into a system in which relationships and patterns are indicated.

• Description - The researcher captures information about objects and data in an observation using natural or artificial language.

• Comparison - the researcher compares the properties of the object he is studying with the properties of other objects.

Theoretical methods:

• Historical method - the researcher studies history in its entirety, generalizes empirical material and establishes on this basis a general historical pattern.

• Ascent from the concrete to the abstract is a method in which the researcher first finds the main connection, and then, step by step, observes how it changes in different conditions and discovers new connections.

• Climbing from the abstract to the concrete is a method of studying reality, the essence of which is the gradual transition from abstract and one-sided ideas about it to its more concrete reproduction in theoretical thinking.

• Formalization is the construction of abstract mathematical models that reveal the essence of the processes being studied.

• Mathematization is the application of methods and concepts of mathematics in the natural, technical and socio-economic sciences for the quantitative analysis of the phenomena they investigate.

There are also general scientific methods of cognition. Among them are:

• Analysis - division of the object into components and detailed study.

• Synthesis is the reconstruction of a complete picture from separate details.

• Analogy is a method of cognition, in which, on the basis of the similarity of objects in some features, one concludes that they are similar in other features.

• Concretization - a deeper study of certain properties.

• Abstraction - the study of the subject from a new angle (with an emphasis on some properties and ignoring others).

• Induction - inferences that are directed from the particular to the general.

• Deduction - inferences that are directed from the general to the particular.

• Idealization - creating an image of a fictional object with ideal properties and using it as a special example.

• Modeling - creating a model of an object for a detailed study of its properties, which is impossible on a real object.

Cognition has two levels (steps): sensual and rational. Let's consider each of them separately.

We will help you consolidate new material in social studies courses at the Skysmart online school.

Sense cognition

Sense cognition occurs with the help of the human senses. The main mechanisms of sensory cognition: sight, hearing, smell, touch, taste.

Forms of sensory cognition:

1. Sensation - a reflection of the individual properties of an object, phenomenon, process that arise as a result of their impact on the senses. With the help of these organs, a person feels some properties of an object - shape, color, smell.

2. Perception is a sensual image of a holistic picture of an object, process, phenomenon that affects the senses. It is perception that helps to form ideas.

3. Representation is a sensuously visual, generalized image of an object, process, phenomenon, which is preserved and reproduced in the mind even without the influence of the objects of knowledge themselves on the sense organs. In other words, what is preserved in the memory of a person after getting to know the subject.

Sensory cognition is always subjective, and it is this level of cognition that realizes the connection of a person with the outside world.

Rational knowledge

Rational knowledge is carried out by reason. It is peculiar only to man and is a rather complicated way of reflecting reality.

Basic mechanisms of rational cognition: comparison, assimilation, generalization, abstraction.

Forms of rational knowledge:

1. A concept is a thought that affirms the general and essential properties of an object.

2. A judgment is a thought that affirms or denies something about an object.

3. Inference (conclusion) - the mental connection of several judgments and the derivation of a new judgment from them.

Example of inference: if a > b and b > c , then a > c .

Types of inference:

1. Inductive reasoning - from particular to general.

2. Deductive reasoning - from the general to the particular.

3. That which is obtained by analogy.

Comparison of sensory and rational cognition

One cannot oppose the sensual and the rational in cognition. Both stages appear as a single process. The difference between them is not temporary, but qualitative: the first stage is the lowest, the second is the highest.

Basic types and forms of knowledge

Knowledge is the result of cognition of reality, the content of consciousness.

Types of knowledge:

1. Worldly - has an empirical character. Based on common sense and ordinary consciousness. This is the most important orienting basis of everyday behavior of people, their relationship with each other and with nature. Leads to a statement of facts and their description.

2. Scientific - understanding of reality in its past, present and future. Provides foresight of various phenomena. Reality is clothed in the form of abstract concepts and categories, general principles and laws, which acquire extremely abstract forms (formulas, graphs, diagrams).

3. Practical - mastering things, transforming the world.

4. Artistic - a holistic display of the world and the person in it. It is built on the image, not on the concept.

5. Rational - reflection of reality in logical concepts and categories. Associated with rational thinking.

6. Irrational - contrary to rational thinking. The subject is emotions, passions, experiences, intuition, will, as well as some phenomena, for example, abnormal ones that do not obey the laws of logic and science.

7. Personal - depends on the abilities of the subject and on the characteristics of his intellectual activity.

Forms of knowledge that are distinguished in relation to scientific knowledge:

• Pre-scientific — prototype, preconditions of scientific knowledge.
• Unscientific - disparate, non-systematic knowledge that is not formalized and not described by laws.
• Parascientific - similar in appearance to scientific knowledge, but incompatible with scientific knowledge.
• Pseudo-scientific - deliberately using conjectures and prejudices.
• Anti-scientific - utopian and deliberately distorting the idea of ​​reality.

arguments for and against why to wear a school uniform

Arguments for school uniform

1. Uniform disciplines

One of the arguments why a school uniform is needed is that it inspires a child with a sense of discipline. Adult life is cited as an example - most professions imply clear rules for dressing, whether it's working in an office, a police station or a fire station.

2. Children do not envy each other

The advantage of a school uniform is that it provides some kind of social equality. If without a dress code, guys can show off with bright clothes or branded items, then everyone is unified with the uniform. However, opponents of the form have a counterargument - we will tell a little further.

3. No need to think about what to wear

Another reason why you need a school uniform is to reduce the time for morning preparations and not distract you from thinking like: “Which is cooler - that purple sweatshirt or a T-shirt with the Fortnite logo?”. The child always knows what clothes to iron for tomorrow, and does not beg for new things to show off in front of classmates.

4. A sense of unity

Prestigious schools in the UK and the US require school uniforms to show belonging to a particular school. So the guys distinguish between "their" and "strangers". From time immemorial, there has been a struggle and confrontation for elite between schools and even universities - and the uniform shows which camp you are from.

Arguments against school uniform

1. Boxing

As a rule, school uniforms do not provide space for self-expression. And it also gives scope for endless nit-picking on the part of the administration - the shirt is not the same, the jacket is not the same, why not in a skirt. Instead of focusing on learning, teachers spend time lecturing about appearance.

2. All the same, there are reasons for envy

Social inequality exists in society, and it cannot be eradicated by uniformity in clothing. Different wealth of families still manifests itself in sophisticated gadgets, travel photos and posts on social networks. It is better to teach children that human qualities are more important than the well-being of the family. Imposing the same dress code will not solve the problem.

3. Not always comfortable to wear

Sitting for seven lessons in a restrictive jacket or meticulously inspecting a chair each time, afraid to leave a snag on tights, is not the most interesting thing to do. Do I need to wear a school uniform when you can wear comfortable jeans with a sweatshirt and not be distracted from the lesson?

4.

The main argument against school uniforms is that it's hard to find a child who says, “I love uniforms! I would wear it all the time!" Most likely, the motivation to study is higher if the student likes the way he looks. For teenagers, appearance is especially important - they want freedom and self-expression, and not a corporate atmosphere.

What to do if you don't like borders

There are many ways to avoid the business dress code, from changing schools to home schooling. Guys who become cramped within the etiquette imposed by the school often take away their documents and start studying at home.

Alyona Rudenko, a graduate of Foxford's home online school, did this — she was shamed at school for her rainbow hair.

“The decision to leave school was sudden and rather abrupt. Parents were afraid, but supported, and I breathed a sigh of relief - no one else will scold me for my multi-colored hair and drawings in the classroom.
