Angle Relationships and Measures

The video tutorial covers three fundamental angle facts: angles around a point add up to 360 degrees, angles on a straight line add up to 180 degrees, and vertically opposite angles are equal. The tutorial provides examples and calculations to illustrate these concepts, helping students understand how to find unknown angles using these facts.
