Question

which angles are vertical angles? ∠yxu and ∠wxz, ∠yxu and ∠tux, ∠yxu and ∠wxu, ∠yxu and ∠yxz

Explanation:

Step1: Recall vertical - angles 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 two lines intersect at a point, the angles that are opposite to each other are vertical angles. $\angle YXU$ and $\angle WXZ$ are opposite each other at the intersection of the two lines.

Answer:

$\angle YXU$ and $\angle WXZ$
