Question

Classify the following True or False:

The complement of $90°$ is $90°$.

• A. True
• B. False

Answer 1

The correct option is B False

Given angle: $90°$.

We know that If the sum of the two angles is $90°$, the angles are said to be complementary angles and each angle said to be the complement of the other.

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

Then,

$$\begin{gathered} \mathrm{x}°+90°=90° \\ \Rightarrow \mathrm{x}°=90°-90° \\ \Rightarrow \mathrm{x}°=0° \end{gathered}$$

Hence, the complement of angle $90°$ is $0°$.
