Question

pr and su are parallel lines. which angles are vertical angles? ∠pqt and ∠rqo ∠pqt and ∠pqo ∠pqt and ∠utq ∠pqt and ∠stv

Explanation:

Step1: Recall vertical - angle definition

Vertical angles are formed by two intersecting lines and are opposite each other.

Step2: Identify intersecting - line angles

Lines $\overleftrightarrow{PR}$ and $\overleftrightarrow{SU}$ intersect at point $Q$. $\angle PQT$ and $\angle SQO$ are vertical angles, and $\angle PQO$ and $\angle TQS$ are vertical angles. Also, lines $\overleftrightarrow{PR}$ and $\overleftrightarrow{VO}$ intersect at point $Q$. $\angle PQT$ and $\angle STV$ are vertical angles.

Answer:

$\angle PQT$ and $\angle STV$
