Question

oq and rt are parallel lines. which angles are alternate interior angles? ∠tsp and ∠opn ∠tsp and ∠tsu ∠tsp and ∠qps ∠tsp and ∠ops

Explanation:

Alternate - interior angles are formed when a transversal intersects two parallel lines. They are between the two parallel lines and on opposite sides of the transversal. In the given figure with parallel lines $\overrightarrow{OQ}$ and $\overrightarrow{RT}$ and transversal $\overrightarrow{NU}$, $\angle TSP$ and $\angle QPS$ are between the parallel lines and on opposite sides of the transversal.

Answer:

$\angle TSP$ and $\angle QPS$
