Question

What is the supplement of a right angle?

Answer 1

1. Two angles are supplementary if the sum of their measures is equal to 180^o.
2. The supplement of any angle can be found by subtracting the given angle with 180^o.
3. Therefore, the supplement of a right angle is ${(180-90)}^o={90}^o$

Hence, the supplement of a right angle is 90^o.
