20 points! answer asap! which statement is true about angles 1 and 2? (image below)
a. they are adjacent angles
b. they are complementary angles
c. they are supplementary angles.
d. they are vertical angles.

A. They are adjacent angles

Step-by-step explanation:

Angles 1 and 2 are next to each other, that makes them adjacent angles

A They are adjacent angles    (next to each other and share a side) True

B. They are complementary angles   (add to 90 degrees)  False-  Angle 2 is 90 degrees)

C. They are supplementary angles.  (add to 180) False, they do not form a straight line

D. They are vertical angles.  (opposite angles)  False, they are not made by intersecting lines
