Question

which angles are vertical angles?

Explanation:

Step1: Recall vertical - angle definition

Vertical angles are formed when two lines intersect. They are opposite each other and are congruent.

Step2: Analyze each option

• For $\angle RQT$ and $\angle RQO$, they share a common side and are adjacent, not vertical.
• For $\angle RQT$ and $\angle UTQ$, they are not formed by the intersection of the same two - line pairs.
• For $\angle RQT$ and $\angle PQO$, they are vertical angles as they are formed by the intersection of lines $PR$ and $OV$ and are opposite each other.
• For $\angle RQT$ and $\angle PQT$, they are adjacent angles that form a straight - line, not vertical.

Answer:

$\angle RQT$ and $\angle PQO$
