प्रश्न
Construct the 90° angle, using ruler and a pair of compass only.
उत्तर
Steps of Construction:
To construct an angle of 90°.
- With O as a center, draw an arc to cut OA at B.
- With B as a centre, draw the same size arc to cut the previous arc at C.
- Again with C as centre and with the same radius, draw one more arc to cut the first arc at D.
- With C and D as centres, draw two arcs of equal radii to cut each other at point E.
- Join O and E, Then, ∠AOE = 90°.
