Question

which angles are vertical angles? ∠pqt and ∠stq ∠pqt and ∠rqo ∠pqt and ∠utv ∠pqt and ∠pqo

Explanation:

Step1: Recall vertical - angle definition

Vertical angles are formed when two lines intersect. They are opposite each other and are equal in measure.

Step2: Analyze the given angles

In the figure, lines $PR$ and $OV$ intersect at point $Q$, and lines $SU$ and $OV$ intersect at point $T$. $\angle PQT$ and $\angle RQO$ are opposite each other at the intersection of lines $PR$ and $OV$.

Answer:

$\angle PQT$ and $\angle RQO$
