Question

which angles are vertical angles? ∠wvx and ∠wvs ∠uvx and ∠rsq ∠uvx and ∠wvs ∠rsq and ∠wvx

Explanation:

Step1: Recall vertical - angle definition

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

Step2: Analyze the given angles

In the given figure, when lines $RT$ and $UW$ are intersected by line $QX$, $\angle RSQ$ and $\angle WVX$ are opposite each other at the intersection - like points of the lines.

Answer:

$\angle RSQ$ and $\angle WVX$
