What is a Regular Polygon?
A regular polygon is a closed shape where all sides are the same length and all interior angles are equal. Examples include equilateral triangles, squares, pentagons, etc.

Pro Tips
n must be at least 3.
As n approaches infinity, the shape and area approach those of a circle.
The sum of interior angles is (n - 2) * 180°.
