This document defines and provides examples of polygons, including regular polygons which have equal angles and sides. It discusses interior and exterior angles of polygons, noting that the sum of interior angles of an n-sided polygon is (n-2)×180 and the sum of exterior angles is always 360 degrees. A relationship is provided that the interior angle and exterior angle at the same vertex of any polygon form a linear pair that sum to 180 degrees.
