Question

Construct an angle of 45° at the initial point of a given ray and justify the construction
Construct the angles of the following measurements:​

Answer 1

Step-by-step explanation:

First, draw a ray OA with intial point O.

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

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