Question

name the angle included by the sides $overline{pn}$ and $overline{nm}$. angle n angle m angle p none of these

Explanation:

Step1: Recall angle - side relationship

The angle included by two sides of a triangle is the angle whose vertex is the common - point of the two sides.

Step2: Identify common vertex

The common vertex of sides $\overline{PN}$ and $\overline{NM}$ is point $N$. So the angle included by $\overline{PN}$ and $\overline{NM}$ is $\angle N$.

Answer:

A. Angle N
