Question

pr and su are parallel lines. which angles are alternate exterior angles? ∠utq and ∠utv ∠utv and ∠stv ∠pqo and ∠utv ∠pqo and ∠stv

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 $\overleftrightarrow{PR}$ and $\overleftrightarrow{SU}$ and transversal $\overleftrightarrow{OV}$, $\angle PQO$ and $\angle UTV$ are alternate - exterior angles.

Answer:

$\angle PQO$ and $\angle UTV$
