What is the sum of two supplementary angles?

90 degrees
180 degrees
270 degrees
360 degrees

The correct answer is: 180 degrees

Supplementary angles are defined as two angles whose measures add up to 180 degrees. This relationship arises from the fact that when two angles are supplementary, they create a straight line together. Therefore, if you take any two angles that fit this description, their sum will always equal 180 degrees. Thus, when considering the sum of two supplementary angles, the correct answer is indeed 180 degrees. The other options represent different relationships among angles: 90 degrees refers to complementary angles that add up to a right angle, while 270 degrees and 360 degrees do not apply to the definition of supplementary angles.
