How are angle 1 and angle 2 related?
a. they are supplementary
b. they are complementary
c. they are vertical.
d. they are adjacent

Considering that the two angles are opposite by the same vertex, they are vertical, hence option C is correct.

When two angles are opposite by the same vertex, they are congruent, that is, they have the same measure, and are called vertical angles.

The answer is the option C

They are vertical

Step-by-step explanation:

we know that

Vertical Angles are the angles opposite each other when two lines cross. They always are equal

therefore

-----> because they are vertical angles
