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. Here, the vertex of the marked angle is C, so one way to name it is $\angle C$.

Step2: Use three - point naming

We can also name the angle using three points. The middle point is the vertex of the angle. So another way to name the marked angle is $\angle BCD$.

Answer:

$\angle C$, $\angle BCD$
