Question

which angles are alternate interior angles? ∠rqn and ∠onq ∠rqn and ∠rqs ∠rqn and ∠mnq ∠rqn and ∠pqn

Explanation:

Step1: Recall alternate - interior angles definition

Alternate - interior angles are between two parallel lines and on opposite sides of a transversal.

Step2: Analyze the given angles

In the figure, lines $MO$ and $PR$ are intersected by transversal $LS$. $\angle RQN$ and $\angle ONQ$ are between $MO$ and $PR$ and on opposite sides of $LS$.

Answer:

$\angle RQN$ and $\angle ONQ$
