Question

which is a pair of vertical angles?

∠vru and ∠srt

∠trs and ∠vrw

∠trv and ∠wru

∠wrv and ∠srw

Explanation:

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

• For $\angle VRU$ and $\angle SRT$: They are not opposite each other formed by the intersection of two lines.
• For $\angle TRS$ and $\angle VRW$: They are not opposite each other formed by the intersection of two lines.
• For $\angle TRV$ and $\angle WRU$: These two angles are opposite each other formed by the intersection of lines $TV$ and $WU$ at point $R$.
• For $\angle WRV$ and $\angle SRW$: They are adjacent angles, not vertical angles.

Answer:

$\angle TRV$ and $\angle WRU$
