## What is a two-dimensional shape?

In geometry, a two-dimensional shape can be defined as a flat plane figure or a shape that has two dimensions – length and width.
Two-dimensional or 2-D shapes do not have any thickness and can be measured in only two faces.

We can classify figures on the basis of the dimensions they have.

A circle, triangle, square, rectangle and pentagon are examples of two-dimensional shapes.

 Fun Facts A point is zero-dimensional, while a line is one-dimensional, for we can only measure its length.

## Let's sing!

2-D shapes can be drawn flat on a plane,
Length and width are dimensions that are main!

## Let's do it!

Instead of handing out colouring 2D shapes worksheets, show you child pictures of two-dimensional  and three- dimensional shapes. Ask them to identify each as two- and three- dimensional and justify their answers.
