Two angles put together to create a 180 degree angle.Supplementary angles add up to 180 degrees as for example the supplementary angle of 120 degrees is 60 degrees because 120+60 = 180 degrees.
When 2 or more angles add up to 180 degrees they are said to be supplementary. Supplementary angles only occur on straight lines, so if one angle is said to be 120 the other angle has to be 60 degrees in order to form a straight line and also to add the angles to 180 degrees
the other angle has to be 120 degrees, so that both angles add up to 180 degrees.
Supplementary angle
It is complementary to one angle, supplementary to another.
It is 120-degree angle are supplementary.
120
180-120 = 60 degrees.
120 degrees.
The supplement to that angle is 60 degrees.

Supplementary angle add to 180 degrees. So the supplement to a 60 deg angle is 180 - 60 = 120 degrees.
yes it is.for example 120 degrees and 60 degrees
120 (2/3 of 180)
