Question

construct and angle 90 degree with the help of scale and compass​

Answer 1

Answer:

Construction of angle 90-degree (90°)

Draw a line segment OA

Taking O as center and using a compass draw an arc of some radius, that cuts OA at B

Taking B as center and with the same radius draw another arc, that cuts the first arc at C

Taking C as center and with same radius draw an arc, that cuts the first arc at D

Now taking C and D as centers and radius greater than the arc CD, draw two arcs, such that they intersect at E.

Join OE such that ∠AOE is a 90-degree angle

Answer 2

Answer:

Draw a line segment OA.

Taking O as center and using a compass draw an arc of some radius, that cuts OA at B.

Taking B as center and with the same radius draw another arc, that cuts the first arc at C.

Taking C as center and with same radius draw an arc, that cuts the first arc at D.
