Question

angle of 90° at the initial point of a given ray and justify the construction

​

Answer 1

Step-by-step explanation:

Steps of Construction:

First draw a ray OA with initial point O.

Taking O as centre and some radius, draw an arc of a circle, which intersects OA, say at a point B.

Taking B as centre and with the same radius as before, draw an arc intersecting the previous arc, say at a point C.

Answer 2

Answer:

Steps of Construction:

First draw a ray OA with initial point O.

Taking O as centre and some radius, draw an arc of a circle, which intersects OA, say at a point B.

Taking B as centre and with the same radius as before, draw an arc intersecting the previous arc, say at a point C.
