Question

name the marked angle in 2 different ways. answer attempt 3 out of 3

Explanation:

Step1: Use vertex - based naming

One way to name an angle is by using the vertex. Here the vertex of the marked angle is O. So we can name it $\angle{O}$.

Step2: Use three - point naming

Another way is to use three points where the middle point is the vertex. For the marked angle, we can name it $\angle{ROP}$ (or $\angle{POR}$) as the rays forming the angle are $\overrightarrow{OR}$ and $\overrightarrow{OP}$.

Answer:

$\angle{O}$, $\angle{ROP}$
