Math CentralQuandaries & Queries


Question from Gretchen, a student:

An angle is its own complement. Find the measure of a suppllement to this angle.


If you have an angle and want to know its complement, you subtract it from 90 degrees. What angle, when subtracted from 90 degrees, gives the same value?

90 - x = x

The supplement of x is the angle that you add to x to make 180 degrees. In other words, 180 - x = the supplement of x.

Does this help?
