Angles in Polygons

We've seen that area is something we can calculate for any shape, but it doesn't tell us much about the shape itself. For example, a hexagon with one unit of area can be regular, with all sides the same length, or it could be highly irregular with no single side-length equal to any other.

In this lesson, we’ll learn to describe shapes by their angles, and we'll discover a property that is fundamental to all polygons.
