Question

which angles are vertical angles? ∠rqn and ∠rqs ∠rqn and ∠onl ∠rqn and ∠pqn ∠rqn and ∠pqs

Explanation:

Step1: Recall vertical - angle definition

Vertical angles are formed when two lines intersect. They are opposite each other and are equal in measure.

Step2: Analyze the given angles

In the figure, lines $MO$ and $PS$ intersect at points $N$ and $Q$ respectively. $\angle RQN$ and $\angle PQS$ are formed by the intersection of lines $MO$ and $PS$. They are opposite each other at the intersection point $Q$.

Answer:

$\angle RQN$ and $\angle PQS$
