Regular polygons are polygons which have all sides equal and and angles equal. We'll dive into all of their basic properties, such as determining the relationship between sides and angles:

We'll even solve some riddles:

I am a peculiar quadrilateral. If you put 3 copies of me together, I can form an equilateral triangle. Similarly, if you put 3 copies of an equilateral triangle together, then they can form me! What quadrilateral am I?

By the end, you'll master complex relationships between these shapes and be able to solve problems like these:

The grey shaded area is what fraction of the larger figure (that is, of the entire stellated pentagon)?
