Answer:
Two Angles are Supplementary when they add up to 180 degrees.
supplementary angles 40 and 140
These two angles (140° and 40°) are Supplementary Angles, because they add up to 180°:
Notice that together they make a straight angle.
supplementary angles 60 and 120
But the angles don't have to be together.
These two are supplementary because
60° + 120° = 180°
