Question from Gretchen, a student: An angle is its own complement. Find the measure of a suppllement to this angle. |
Gretchen,
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?
