Interior & Exterior Angles of Triangles Matching Activity

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

FREE ~ Great practice for my 8th grade math & Geometry students sorting angles created by parallel lines cut by a transversal into the following categories: Corresponding, Alternate Interior, Alternate Exterior, and Same-Side Interior
