Question

name the marked angle in 2 different ways.

Explanation:

Step1: Name by vertex

When naming an angle by its vertex, if there is only one angle at that vertex, we can use the vertex - point. Here, the vertex is B, so one way to name the angle is $\angle B$.

Step2: Name by three - point system

In the three - point system, the vertex must be the middle point. The rays that form the angle are part of the lines starting from the vertex. So, another way to name the angle is $\angle EBC$.

Answer:

$\angle B$, $\angle EBC$
