Question

name the marked angle in 2 different ways. answer attempt 1 out of 2

Explanation:

Step1: Use vertex - based naming

We can name the angle using the vertex. Since the vertex of the marked angle is D, one way to name it is $\angle D$.

Step2: Use three - point naming

We can also name the angle using three points. Taking a point on one ray (say B), the vertex D, and a point on the other ray (say E), we can name it $\angle BDE$.

Answer:

$\angle D$, $\angle BDE$
