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
Understanding Interior and Exterior Angles in Triangles
These hands on geometry lessons are such a great way to help kids see the relationship between the interior and exterior angles in triangles! This free download is simple to use and includes teaching tips and an answer key!
Get students out of their seats and writing equations to solve for missing angle measures with this interactive angle relationships scavenger hunt. Students will practice writing equations to determine angles measures given algebraic expressions to represent angles. Students will be able to solve for x or a missing angle given parallel lines cut by a transversal (with congruent or supplementary pairs), interior and/or exterior angle measures of a triangle and more.
