Question
Construct the angles of the following measurements:
30°

Answer


Steps of construction:
  1. Draw a line segment AB.
  2. Keeping A as the centre and any radius draw an arc which intersects AB at C.
  3. Keeping C as center and the same radius draw an arc which intersects the previous arc at D.
  4. Keeping D and C as center and radius more than half of DC draw arcs which intersect each other at E.
  5. Join EA.
Therefore $\angle\text{EAB}=30^\circ $
