Answer:
True, because they are under 180 degrees
"Supplementary angles are two angles with a sum of 18 0 ∘ 180 ^\circ 180∘ . A common case is when they lie on the same side of a straight line."
Step-by-step explanation:
They are supplementary because 60 +120 is 180, which is what supplementary means.
They are not adjacent, they do not touch and share no common vertex or side.
