How are ∠1 and ∠2 related?
An image is shown of three intersecting lines.
Two of the lines form an upper X shape and the third line runs close to horizontal.
Six angles are formed at the shared intersection point of all three lines.
Angle 1 is formed by the third line and the downward sloped line that forms the upper X.
Each angle is labeled consecutively around the intersection point in a clockwise order.
A. They are supplementary.
B. They are complementary.
C. They are vertical.
D. They are adjacent.
