Question

mo and pr are parallel lines. which angles are vertical angles? ∠onq and ∠pqs ∠onq and ∠mnq ∠onq and ∠pqn ∠onq and ∠mnl

Explanation:

Step1: Recall the definition of vertical angles

Vertical angles are a pair of non - adjacent angles formed by the intersection of two lines.

Step2: Analyze each option

• For $\angle ONQ$ and $\angle PQS$: They are not formed by the intersection of the same two lines.
• For $\angle ONQ$ and $\angle MNQ$: They are adjacent angles (share a common side).
• For $\angle ONQ$ and $\angle PQN$: They are adjacent angles (share a common side).
• For $\angle ONQ$ and $\angle MNL$: $\angle ONQ$ and $\angle MNL$ are formed by the intersection of lines $SO$ and $PM$ (or $PR$). They are non - adjacent and opposite each other at the intersection of the two lines.

Answer:

$\angle ONQ$ and $\angle MNL$
