Solution
Steps for the construction of a 30° angle:
1: Draw a ray OA.
5: With O as centre and any suitable radius draw an arc above OA cutting it at a point B.
2: With B as centre and the same radius as before, draw another arc to cut the previous arc at C.
4: Join OC and produce it to D.
3: Draw the bisector OE of ∠AOD.
Then, ∠EOA = 30°
