Question

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

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 diagram with parallel lines $\overleftrightarrow{OQ}$ and $\overleftrightarrow{RT}$ and transversal $\overleftrightarrow{NU}$, $\angle RSU$ and $\angle QPN$ are outside the parallel - lines and on opposite sides of the transversal.

Answer:

$\angle RSU$ and $\angle QPN$
