Chapter 7 Polygons
... The sum of the interior angles of a polygon changes with the number of sides. But the sum of the exterior angles always measure 360˚. That’s important to know. Assume I have a regular polygon whose exterior angle measured 40˚ and I wanted to know how many sides the polygon had, could I make that det ...
