Question 5 (a)
Construct with ruler and compasses, angles of following measures:
60∘
Steps of construction:
(i) Draw a ray ¯¯¯¯¯¯¯¯OA.
(ii) Taking O as centre and convenient radius, mark an arc, which intersects ¯¯¯¯¯¯¯¯OA at P.
(iii) Taking P as centre and the same radius, cut the previous arc at Q.
(iv) Join ¯¯¯¯¯¯¯¯¯OQ. Thus, ∠QOA = 60∘ .
