Question

Construct the angle of the measurement :

 1. 30°

 

Answer 1

 

Steps of construction:
1. Draw a line segment AB.
2. With center A and any radius, draw an arc which intersect AB at C.
3. With center C and same radius, draw an arc which intersects previous arc at D.
4. With centers D and C and radius more than `1/2`DC ,draw arcs intersecting each other at
E
5. Join EA
∴ `∠`EAB = 30°
