Question

An angle which can be constructed using a pair of compass and ruler is ______ .

• A. ${20}^0$
• B. ${80}^0$
• C. ${60}^0$
• D. ${110}^0$

Answer 1

The correct option is C ${60}^0$

$\Rightarrow$ An angle which can be constructed using a pair of compass and ruler is ${60}^o$.

$Step1:$ Draw the arm AB.

$Step2:$ Place the point of the compass at A and draw an arc that passes through B.

$Step3:$ Place the point of the compass at B and draw an arc that passes through A. Let this arc cut the arc drawn in Step 2 at P.

$Step4:$ Join A to P. $\angle PAB={60}^o$.
