Which relationship describes angles 1 and 2? select each correct answer. a)adjacent angles b)supplementary angles c)complementary angles d)vertical angles

Hey there!

As you can see, they are lying on the same line.

When two angles are on the same straight line, they are adjacent. 

Adjacent angles are supplmentary. 

Adjacent angles= 180 degrees Supplementary= 180 degrees

They are choices "A" and "B". 

I hope this helps!
