Question

name the marked angle in 2 different ways.

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 N, so one name is $\angle N$.

Step2: Use three - point naming

An angle can also be named using three points where the middle point is the vertex of the angle. For the marked angle with vertex N, two rays are part of the angle. Using points Q, N, and O (where N is the vertex), another name is $\angle QNO$.

Answer:

$\angle N$, $\angle QNO$
