Question

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

Explanation:

Step1: Use vertex - based naming

An angle can be named using the vertex point. Here the vertex of the marked angle is point O. One way to name it is $\angle{NOQ}$ where the middle letter is the vertex and the other two are points on the rays forming the angle.

Step2: Use single - letter naming (if applicable)

If there is only one angle at a vertex, it can be named by the vertex letter alone. But here there are multiple angles at vertex O. So we use another vertex - based name $\angle{QON}$.

Answer:

$\angle{NOQ}$, $\angle{QON}$
