classification of shapes

 Hi all, hope you are doing well.

Mathematics is an interesting area,

It's fun to dive into it.

Let's start today's topic. SHAPES

What is a shape?

SHAPE is the outline of something.

The shapes are closed by outline made by points, line segments or curved lines.

we can see different objects in our daily life are in different shapes such as birthday cap, ruler, photo frame, wall clock etc

In this figure we can see basic shapes such as circle, square, triangle, Rectangle etc.

A closed figure or closed shape can be defined as any geometric shape which starts and ends at the same point to form a boundary by line segments or by curves. 

Shapes shown in the above picture are closed figures.

Open figures are incomplete shapes. An open figure’s starting and endpoints are different.

Classification of shapes

Depend upon its regularity or uniformity shapes are divided into two

1. Regular shapes 

2.Irregular shapes

A regular shape is usually symmetrical .

Examples are square, circle, etc. 

Irregular shapes are asymmetrical. They are also called free form shapes or organic shapes. 

 Example, the shape of a tree and rocks are irregular or organic.

Depend upon the dimension shapes are divided into two

1. Two Dimensional shapes

2. Three Dimensional shapes

 The two-dimensional shapes are flat shapes , closed figures or plane shapes . Examples are circles, squares, rectangles, rhombus, etc.

The three-dimensional shapes are solid shapes.

Examples are cube, cuboid, cone, sphere and cylinder.

Types and properties of geometrical shapes are different
