# Explore Exterior Interior, Boathouse, and more!

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!

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

Two pages of introduction to polygon vocabulary, interior angle sum, exterior angles, naming, and parts of the polygon. Twelve practice problems involve solving from variables, determining the number of sides of a polygon, and finding interior and exterior angles. Answer key included. The one-page reference sheet is a great way for SPED and ESL/ESOL students to have a quick way to access the information they need for polynomials. Happy Solving! from the miss jude math! shop
