Question

To construct an angle of $30°$, we construct the angle bisector of

• A. $15°$
• B. $60°$
• C. $30°$
• D. none of these

Answer 1

The correct option is B

$60°$

Explanation for correct option:

We know that the angle bisector divides the angle into two equal parts.

So, two construct an angle of $30°$, we have to bisects an angle that is double of $30°$.

Double of $30°$ = $2\times 30°=60°$.

So, two construct an angle of $30°$, we have to bisects an angle of $60°$.

Hence, option(B) is the correct answer.
