Question

name the marked angle in 2 different ways.

Explanation:

Step1: Use vertex - only naming

When the vertex has only one angle, we can name the angle by its vertex. Here, the vertex of the marked angle is B, so one way to name it is $\angle B$.

Step2: Use three - point naming

We can name the angle using three points where the middle point is the vertex of the angle. For the marked angle, we can name it $\angle EBC$ (assuming the marked angle is the one between rays BE and BC).

Answer:

$\angle B$, $\angle EBC$
