Question

Classify the following True or False:

The supplement of a right angle is also a right angle.

• A. True
• B. False

Answer 1

The correct option is A True

Given angle is a right angle and measure of right angle is $90°$.

We know that If the sum of the two angles is $180°$, the angles are said to be supplementary angles and each angle said to be the supplement of the other.

Let $\mathrm{x}°$ be a supplement of angle $90°$.

Then,

$$\begin{gathered} \mathrm{x}°+90°=180° \\ \Rightarrow \mathrm{x}°=180°-90° \\ \Rightarrow \mathrm{x}°=90° \end{gathered}$$

Thus, the supplement of angle $90°$ is $90°$.

Hence, the supplement of a right angle is also a right angle.
