In this topic, you are going to explore the exterior angles of polygons. You will need your knowledge of angle relationships to help you solve numeric and algebraic problems regarding the exterior angles of polygons.

Essential Question

 

Warm-Up

Determining Exterior Angle Measures

Warm-up iconYour knowledge of linear pairs is going to help you solve questions regarding the exterior angles of polygons. You have learned in previous topics that linear pairs are supplementary. A form of a linear pair is when you have an exterior angle and its corresponding interior angle. Before you learn more about the exterior angles of polygons, see if you can determine the exterior angles of three different polygons in this non-graded activity. Click the player button to begin.
