Question

which angles are alternate exterior angles?
∠pqn and ∠mnq
∠pqn and ∠mnl
∠rqs and ∠mnl
∠pqs and ∠pqn

Explanation:

Alternate exterior angles are formed when a transversal crosses two parallel lines. They are on opposite sides of the transversal and outside the two lines.

• $\angle RQS$ and $\angle MNL$ fit this definition as they are on opposite sides of the transversal $SL$ and outside the parallel lines $PR$ and $MO$.
• $\angle PQN$ and $\angle MNQ$ are alternate interior angles.
• $\angle PQN$ and $\angle MNL$ are not in the alternate exterior position.
• $\angle PQS$ and $\angle PQN$ are adjacent angles.

Answer:

$\angle RQS$ and $\angle MNL$
