Angle Relationships and Properties

The video tutorial covers various methods to name angles, including using numbers, vertices, and points on rays. It explains how to measure angles using a protractor and classify them as obtuse, acute, or right. The tutorial also discusses identifying congruent angles through diagrams and using the angle addition postulate to find unknown angle measures. Finally, it demonstrates how to calculate angle measures using bisectors.
