Question

What is the angle measure for $\frac{1}{3}$ of a right angle?

• A. ${30}^{\circ }$
• B. ${45}^{\circ }$
• C. ${60}^{\circ }$
• D. ${90}^{\circ }$

Answer 1

The correct option is A ${30}^{\circ }$

The measure of right angle is ${90}^{\circ }$.
We need to find $\frac{1}{3}$ of a right angle.
$\begin{array}{cc}\frac{1}{3}\times {90}^{\circ }& ={90}^{\circ }÷3\\ & ={30}^{\circ }\end{array}$
