Question

Construct the 90° angle, using ruler and a pair of compass only.

Answer 1

Steps of Construction:

To construct an angle of 90°.

1. With O as a center, draw an arc to cut OA at B.
2. With B as a centre, draw the same size arc to cut the previous arc at C.
3. Again with C as centre and with the same radius, draw one more arc to cut the first arc at D.
4. With C and D as centres, draw two arcs of equal radii to cut each other at point E.
5. Join O and E, Then, ∠AOE = 90°.
