This is a 45 page Smartboard file explaining how the polygon angle sum theorem works. In the lesson is an explanation between regular and irregular polygons, convex and concave polygons, and the names of the most commonly used polygons. Students then learn how to find the total amount of degrees in polygons using the formula and how to find the measurement of just one angle in a regular polygon.
