Question

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

Explanation:

Step1: Use vertex - point naming

An angle can be named using the vertex point in the middle and a point on each ray. Here the vertex is O, and points on the rays are N and Q. So one name is $\angle NOQ$.

Step2: Use just the vertex

If there is only one angle at a vertex, it can be named by just the vertex. Since there is only one marked angle at vertex O, it can also be named $\angle O$.

Answer:

$\angle NOQ$, $\angle O$
