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.

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