---A linear pair forms a line, which is equal to 180 degrees
#4. Adjacent
#5. Vertical, Complementary
#6. Vertical, Supplementary
---There is a 90 degree angle within this problem. If one angle is 90 degrees, then they are all 90 degrees, which makes the sum of angle 1 and 2 = 180. So, they are supplementary.
