What is a regular polygon?

Back

A regular polygon is a polygon that is both equilateral (all sides are equal) and equiangular (all angles are equal).

What does congruent mean in geometry?

Back

Congruent means that two figures have the same shape and size.

Front

How can you determine if two polygons are congruent?

Back
