Question

name the marked angle in 2 different ways.

Explanation:

Step1: Use vertex - based naming

An angle can be named by its vertex when there is only one angle at that vertex. If the marked angle has vertex B, one way to name it is $\angle B$.

Step2: Use three - point naming

An angle can also be named using three points, with the vertex in the middle. If the marked angle has points B, E, and C (for example, assuming the sides of the angle pass through these points), it can be named $\angle EBC$.

Answer:

$\angle B$, $\angle EBC$
