Question

which angles are vertical angles? ∠onq and ∠pqn ∠onq and ∠pqs ∠onq and ∠mnq ∠onq and ∠mnl

Explanation:

Step1: Recall vertical - angle definition

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

Step2: Analyze the given angles

In the figure, lines $MO$ and $PR$ are intersected by line $LS$. $\angle ONQ$ and $\angle MNL$ are formed by the intersection of lines $MO$ and $LS$. They are opposite each other at the intersection point $N$.

Answer:

$\angle ONQ$ and $\angle MNL$
