Answer:

  C.  Vertical angles are supplementary if both are right angles.

Step-by-step explanation:

You want to know the conditions when vertical angles are supplementary.

Supplementary angles

Two angles are supplementary when they total 180°.

Vertical angles

Vertical angles are formed when two lines cross. They share a vertex, but not a side. Their sides are opposite rays.

Vertical angles are always congruent.

Supplementary vertical angles

If x is the measure of one of two supplementary vertical angles, then we must have ...

  x + x = 180°

  2x = 180° . . . . . collect terms

  x = 90° . . . . . . . divide by 2

Vertical angles will be supplementary if and only if they are both right angles.
