Question

name the marked angle in 2 different ways.

Explanation:

Step1: Identify the vertex of the angle

The marked angle has its vertex at point B. The two sides of the angle are formed by segments BA and BC.

Step2: Name the angle using the vertex letter

One way to name the angle is by using the vertex letter, so it can be named $\angle B$.

Step3: Name the angle using three points

Another way is to use the three points that form the angle, with the vertex in the middle. So it can be named $\angle ABC$ (or $\angle CBA$).

Answer:

$\angle B$, $\angle ABC$ (or $\angle CBA$)
