Question

pr and su are parallel lines. which angles are alternate interior angles? ∠utq and ∠rqt ∠utq and ∠stv ∠utq and ∠pqt ∠utq and ∠utv

Explanation:

Alternate - interior angles are formed when a transversal intersects two parallel lines. They are non - adjacent angles between the two parallel lines and on opposite sides of the transversal. In the given figure with parallel lines $\overleftrightarrow{PR}$ and $\overleftrightarrow{SU}$ and transversal $\overleftrightarrow{OV}$, $\angle UTQ$ and $\angle RQT$ are non - adjacent, between the parallel lines, and on opposite sides of the transversal.

Answer:

$\angle UTQ$ and $\angle RQT$
