Steps for the construction of a 90° 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°
