Question

which is a pair of vertical angles?

∠vru and ∠srt
∠trs and ∠vrw
∠trv and ∠wru
∠wrv and ∠srw

Explanation:

Step1: Recall the definition of vertical angles

Vertical angles are a pair of non - adjacent angles formed by the intersection of two lines. They are opposite each other.

Step2: Analyze each option

• For $\angle VRU$ and $\angle SRT$: They are adjacent, not vertical angles.
• For $\angle TRS$ and $\angle VRW$: They are not formed by the intersection of two lines in the vertical - angle - forming way.
• For $\angle TRV$ and $\angle WRU$: They are not vertical angles.
• For $\angle WRV$ and $\angle SRW$: They are adjacent, not vertical angles.

Wait, let's re - check. The correct pair of vertical angles is $\angle TRS$ and $\angle VRW$. When two lines intersect (assuming the lines are such that $\angle TRS$ and $\angle VRW$ are formed by the intersection of two lines), vertical angles are equal and non - adjacent.

Answer:

$\angle TRS$ and $\angle VRW$
