Answer :

Step 1: Construct a line segment or arbitrary length an take an semi-circular arc on the line

Step 2: Taking the same radius, an arc is cut on the semi-circular arc to give 60°

Step 3: The 60° thus formed is bisected by taking any arbitrary radius and cutting of arcs centring at the two intersection points to yield a 3rd intersection

<MAB = 60°

Step 4: The deeper point of intersection is joined with point A and thus the angle is bisected to give 30°

<MAB = 60°

<NAB = 30°
