Understand the Relationship Between Exterior Angles

This video tutorial covers the concept of exterior angles in triangles, explaining how they relate to the interior angles. It reviews the basic properties of triangle angles, introduces the exterior angle theorem, and demonstrates how to apply this theorem to solve problems. The tutorial concludes with a practical application, showing how to use exterior angles in real-world scenarios, such as designing a skateboard ramp.
