This concept teaches students how to calculate the sum of the interior angles of a polygon and the measure of one interior angle of a regular polygon.
This video gives more detail about the mathematical principles presented in Basic Geometric Definitions.
Ten question quiz. Students must use their knowledge of the sum of interior angles of convex polygons to solve for the sums of various polygons and missing angles. For two problems students must set up and solve algebraic equations. For one questions students must explain and give an example of why the formula does not work for concave polygons.
