Question

card letter: g answer from previous card: 90° complimentary next question: one set of vertical angles in the drawing below are...

Explanation:

Step1: Recall vertical - angles definition

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

Step2: Identify vertical - angle pairs in the drawing

In the drawing where two lines intersect, if we assume the angles are named as $\angle A$, $\angle B$, $\angle C$, $\angle D$ (where $\angle A$ and $\angle C$ are opposite, and $\angle B$ and $\angle D$ are opposite), one set of vertical angles could be $\angle A$ and $\angle C$ (or $\angle B$ and $\angle D$). Without specific angle - naming in the given drawing, we just know the concept. For example, if the intersection of the two lines creates angles at the intersection point, a pair like $\angle K$ and the angle opposite to it across the intersection are vertical angles.

Answer:

One possible set of vertical angles (assuming appropriate angle - naming in the drawing) is the pair of angles that are opposite each other at the intersection of the two lines.
