# Geometrical Shapes and Solids for Class 1

## Geometric Shape

A geometric shape is an object with a fixed structure. These shapes are made up of lines, curves, angles, and surfaces. Square, rectangle. circles are two-dimensional (flat) shapes. Some other two-dimensional shapes are as follows:

Line

A line is a straight, one-dimensional geometric shape that can go on forever in both directions.

Straight Line

Any line without any curves is said to be straight. It can be divided into three categories:

Slanting Line:

A straight line that leans or slants in a different direction is known as a slanting line.

Vertical Line

It is a straight line that connects the bottom to the top.

Horizontal Line

It is a straight line that moves in both right- and left-handed directions.

We can understand the shape of a figure by using some prefixes, such as:

Tri – 3

Penta – 5

Hexa – 6

Hepta – 7

Octa – 8

And a lot more…

Example: Which figure shows an Octagon?

a)
b)
c)
d)

Explanation: The polygon made up of eight line segments is known as Octagon.

## 3D Shapes or Geometric solid

A geometric solid, also known as a 3D shape or a 3D object, is a mathematical shape that has three dimensions: length, width, and height. In 3D, D stands for Dimensional. These 3-D shapes are not flat like 2D shapes (which have only length and width) but instead have depth or thickness, which makes them look like real objects you can touch and hold.

For example:

The primary three-dimensional shapes that surround us are cubes, cuboids, cones, spheres and cylinders.

Example: How many circles are present in the figure given below?

a) 2
b) 3
c) 4
d) 5

Explanation: We can count that there are 5 circles.
