Question

oq→ and rt→ are parallel lines. which angles are alternate exterior angles? ∠qpn and ∠qps ∠qpn and ∠rsp ∠qpn and ∠rsu ∠qpn and ∠ops

Explanation:

Alternate - exterior angles are formed when a transversal intersects two parallel lines. They are outside the two parallel lines and on opposite sides of the transversal. In the given figure with parallel lines $\overleftrightarrow{OQ}$ and $\overleftrightarrow{RT}$ and transversal $\overleftrightarrow{NU}$, $\angle QPN$ and $\angle RSU$ are outside the parallel lines and on opposite sides of the transversal.

Answer:

$\angle QPN$ and $\angle RSU$
