Question

name the marked angle in 2 different ways.

Explanation:

Step1: Use vertex - based naming

We can name an angle by its vertex when there is only one angle at that vertex. Here the vertex is \(N\), so one way to name the angle is \(\angle N\).

Step2: Use three - point naming

We name an angle using three points where the middle point is the vertex. For the marked angle, with vertex \(N\) and rays \(NL\) and \(NM\), we can name it \(\angle LNM\) or \(\angle MNL\).

Answer:

\(\angle N\), \(\angle LNM\)
