Question

which angle number represents an angle vertical to ∠lrk? answer attempt 1 out of 2 submit answer

Explanation:

Step1: Recall vertical - angle definition

Vertical angles are formed when two lines intersect. They are opposite each other and are congruent.

Step2: Identify intersecting lines

Lines $LK$ and $NP$ intersect at point $R$. $\angle LRK$ and $\angle NRP$ are vertical angles. Also, $\angle LRK$ and $\angle NRP$ are opposite each other at the intersection of the two lines. In the given number - labeled angles, $\angle 4$ is the same as $\angle NRP$.

Answer:

4
