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.
