Angles of Triangles: Interior and Exterior Angle Measures

The video tutorial covers the concepts of interior and exterior angles of triangles. It explains that the sum of the interior angles of a triangle is always 180 degrees, regardless of the triangle's size. The tutorial demonstrates how to find a missing interior angle using this theorem. It also introduces the exterior angle theorem, which states that an exterior angle is equal to the sum of the two non-adjacent interior angles. The video provides examples and exercises to help viewers understand and apply these theorems to solve for unknown angles.
