Question

name the marked angle in 2 different ways.

Explanation:

Step1: Use vertex - based naming

One way to name an angle is by using the vertex. Here the vertex is O. So we can name the angle as $\angle NOQ$.

Step2: Use three - point naming

Another way is to use three points on the angle. We can name it as $\angle QON$.

Answer:

$\angle NOQ$, $\angle QON$
