## About the Triangle Angle Sum Worksheet

Before we delve any further, what is the triangle sum theorem? We know all about triangles; they’re pretty shapes with three sides. However, the triangle angle sum theorem states that the sum of the three interior angles in a triangle is always 180°. ALWAYS. It also goes further to state that the measure of the exterior angle is equal to the sum of its two opposite interior angles.

The formula for this theorem is pretty simple:

For a triangle ABC, we have A+B+C = 180°

The triangle sum theorem has varied applications and can even be extended to problems involving other polygons.
