Understanding Angles in Triangles

This video tutorial covers the properties of interior and exterior angles of triangles. It explains how to calculate missing angle measures using equations and applies these concepts to solve real-life problems, such as determining angles in the Bermuda Triangle. The tutorial emphasizes the sum of interior angles being 180 degrees and how exterior angles relate to non-adjacent interior angles.
