Question

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

Explanation:

Step1: Use vertex - centered naming

An angle can be named by the vertex if there is only one angle at that vertex. Here, the vertex of the marked angle is N. So one way is $\angle N$.

Step2: Use three - point naming

For an angle, we can name it using three points where the middle point is the vertex of the angle. For the marked angle with vertex N, we can name it $\angle PNO$ or $\angle ONP$.

Answer:

$\angle N$, $\angle PNO$
