Let's start with Naming angles. Step 1: Naming angles using three letters An angle is named using three capital letters. The middle letter must be the vertex (the point where the two rays meet), and the other two letters are points on each of the rays. For example, if the vertex is point B, and there are points A and C on the rays, the angle can be named ABC or CBA. Step 2: Naming angles using one letter If there is only one angle at a vertex, you can sometimes name the angle using just the vertex letter. For example, if point B is the vertex and there's only one angle there, you can call it B. However, this can be ambiguous if multiple angles share the same vertex. Step 3: Example Consider an angle with vertex P, and points Q and R on its rays. The angle can be named QPR or RPQ. If there is only one angle at vertex P, it can also be named P.
