Question

Construct with ruler and compasses, angle of the following measure:
${30}^o$

Answer 1

Step 1: A ray from $O$ is drawn.

Step 2: An arc of ${60}^{\circ }$ is drawn using compass.

Step 3:Construct a perpencicular bisector to the arc from $0^{\circ }$ Join $OA$

$\therefore \angle AOX={30}^{\circ }$

Thus,$\angle AOX$ is the required angle making ${30}^{\circ }$
