Applet informally illustrates to the student that the sum of the measures of the interior angles of any quadrilateral is 360 degrees, and that the sum of the measures of the exterior angles of any quadrilateral is 360 degrees. This applet is a revision of the one found at http://tube.geogebra.org/m/1878165. It was revised in order to help students develop the formula for the sum of the measures of the interior angles of any n-gon = 180(n - 2).

This matching activity is a great way to have students practice finding unknown measures of interior and exterior angles of triangles. There are 12 problems students will solve and match up the answers to on the mat. Students need to apply the triangle sum theorem and also use supplementary and complementary angles to solve for the unknown measure. Teacher answer key included!  Common Core Aligned: 8.G.5
