Question

su and vx are parallel lines. which angles are vertical angles? ∠xwy and ∠stw ∠xwy and ∠vwt ∠xwy and ∠utw ∠xwy and ∠str

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 diagram, the intersection of the lines forming the angles needs to be considered. $\angle XWY$ and $\angle STW$ are not vertical angles as they are not formed by the same intersection of lines. $\angle XWY$ and $\angle VWT$ are adjacent angles. $\angle XWY$ and $\angle STR$ are not vertical angles. $\angle XWY$ and $\angle UTW$ are vertical angles because they are formed by the intersection of the trans - versal line and are opposite each other.

Answer:

$\angle XWY$ and $\angle UTW$
