This concept teaches students the sum of exterior angles for any polygon and the relationship between exterior angles and remote interior angles in a triangle.
This video gives more detail about the mathematical principles presented in Exterior Angles Theorems.
This video shows how to work step-by-step through one or more of the examples in Exterior Angles Theorems.
Ten question quiz. Students must solve for missing angles in triangles using the exterior angle theorem of triangles. Students need to use basic arithmetic and algebra skills to solve the problems.
A list of student-submitted discussion questions for Exterior Angles Theorems.
So...does our formula apply only to convex polygons? Or can we fix things up so that it applies to concave polygons also?
This study guide reviews terminology for triangles, different types of triangles, and interior and exterior angles theorems.
