Question

name the marked angle in 2 different ways.

Explanation:

Step1: Use vertex - only naming

If the angle at vertex N is the marked angle, we can name it ∠N since there is only one angle at vertex N in this context.

Step2: Use three - point naming

We can also name the angle using three points. The angle with vertex N and rays NM and NO can be named ∠MNO or ∠ONM.

Answer:

∠N, ∠MNO
