Why is the supplement of an acute angle always obtuse?
An acute angle is an angle that is between 0 and 90 degrees. The supplement of the angle is 180 degrees minus the magnitude of the angle. Since the original angle is greater than 0 degrees, the supplement must be less than 180-0 = 180 degrees. Since the original angle is less than 90 degrees, the supplement must be greater than 180-90 = 90 degrees. Thuis, the supplement measures between 90 and 180 degrees - that is, it is an obtuse angle.
What do you call an angle that is more than 90 degrees and less than 270 degrees?
There is no specific name for an angle between 90 and 270 degrees. Between 90 and 180 it is an obtuse angle. Between 180 and 270 (and up to 360) it is a reflex angle.
Is an acute angle bigger than 90 degrees?
