Angles that add up to 180 degrees are called supplementary angles.
Such angles are called complementary angles.

Angles that add up to 180 degrees are called supplementary angles.
The adjacent Supplementary angles are the sum of 2 angles that make 180 degrees.
Two right angles would always be supplementary because the sum of their angles is 180 degrees.
Supplementary angles are two angles whose measures add to 180 degrees. Adjacent angles are two angles that happen to lie next to each other, so that they combine to form a larger angle whose measure is the sum of the measures of the adjacent angles. Angles may be both adjacent and supplementary, in which case they will form a straight angle.
180 degrees.
Two angles whose sum is 90 degrees are called complementary angles.
Sum of adjacent angles on a straight line.
Two angles the sum of whose measures is 90 degrees are complimentary angles.
Such angles are called complementary angles.
Two angles whose sum is 90 degrees are called complementary angles. Two angles whose sum is 180 degrees are called supplementary angles. A single angle of 90 degrees is called a right angle.
