Question

The supplement of a right angle is always _________ angle.

Answer 1

Any two angles whose sum is $180$ degrees are called supplementary angles.

If $x,y$ are supplementary angles then $x+y=180$ degrees .

So we get, $y=180-x$ ( Here, $y$ is called supplement of $x$ )

or

$x=180-y$ ( Here, $x$ is called supplement of $y$ )

Therefore,

Supplementary of right angle i.e., Supplementary of $90$ degrees $=$$180-90$$=$$90$ degrees.

Therefore, the Supplement of right angle is always a right angle.
