Angle Relationships and Properties

The video tutorial explains how to refer to angles using three letters and provides examples of calculating angles. It covers the concept of angles on a straight line, which always add up to 180 degrees, and explores angles formed by parallel lines. The tutorial also includes solving for unknown angles using given information.
