Question

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

Explanation:

Step1: Use vertex - based naming

An angle can be named by its vertex when there is only one angle at that vertex. Here the vertex of the marked angle is O, so one way is $\angle O$.

Step2: Use three - point naming

An angle can also be named using three points where the middle point is the vertex. For the marked angle, we can name it as $\angle POR$ (the order of the non - vertex points can also be reversed like $\angle ROP$).

Answer:

$\angle O$, $\angle POR$
