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.
