Question

name the marked angle in 2 different ways.

Explanation:

Step1: Use vertex - only naming

When using the vertex - only naming, we can name the angle as $\angle D$.

Step2: Use three - point naming

For three - point naming, we name the angle with the vertex in the middle. So it can be named as $\angle BDC$ (assuming the marked angle is the whole angle at vertex $D$ between rays $DB$ and $DC$).

Answer:

$\angle D$, $\angle BDC$
