Label the angle in three different ways

The video tutorial explains how to label angles in geometry using three methods: by a number inside the angle, by the name of the vertex, and by using three points. It emphasizes the importance of understanding these methods as they may appear in textbooks or tests. The tutorial concludes by highlighting that while the methods differ, they describe the same angle.

Describe the significance of using three points to label an angle.

What might be the reason for using different labeling methods in problems or tests?
