Angles in Polygons

This Angles in Polygons assessment also includes:

Show your class that finding angle measures is a regular calculation with a resource that provides 12 problems dealing with the measures of angles in regular polygons. Pupils use formulas for the sum of measures of angles in a polygon to calculate measures of individual angles or the number of sides in a polygon.
