No. COMPLIMENTARY angles always add up to 90 degrees. SUPPLEMENTARY angles always add up to 180 degrees. you don't really have to know this stuff in later math, but for whatever course you're in right now it would be a vital error to mix them up. but if you are asking if every angle that is supplementary to another is 90 degrees by itself, the answer is still no. a supplementary can be any angle that is less than 180 degrees.

Adjacent angles add up to be 90 degrees?
No. Complementary angles add up to 90 degrees. Supplementary angles add up to 180 degrees.
The supplement of a 65 degree angle has a measure of?
Supplementary angles are angles whose sums =180 degrees. You have a 65 degree angle + it's supplementary angle = 180 degrees. So, to find the supplementary angle, subtract 65 from 180. 180 - 65 = supplementary angle. 115 = supplementary angle. To check, add the angles together. 65 + 115 = 180 (check) (Also, you might be working with complimentary angles. Complimentary angles are angles whose sum = 90 degrees.)
What are supplementary angles?
supplementary angles are angles that have a sum of 180*.another way to remember that its 180* is the two p's in the word make 8.example. 70*+110*= 180* supplementary.Complementary angles add up to 90 degrees.Supplementary angles are two angles whose sum add up to 180 degrees. Can be shown as (180 - x)
What kind of angles have a sum of 180 degrees?
its supplementary because they add up to 180 think of it this way what is a high supplement dose 180 what has to complement each-other 90 so supplementary angles add up to 180 degrees while complementary adds up to 90 degrees
Two angles that fit together to form a right angle?
Those angles are called complimentary angles. They add up to 90 degrees. Two angles that add up to 180 degrees are called supplementary angles.
