Question

Steps for the construction of $\angle AOB={120}^{\circ }$ is given below. Choose the correct order.
1.With Q as the centre and with same radius as in step- 3, draw an arc so as to cut the arc drawn in step - 2. Name the point of intersection as R.
2.With P as the centre, draw an arc with the same radius as in step-2 intersecting the previous arc. Name the point of intersection as R.
3.Draw a ray OB
4.Join points O and R using a scale and a pencil. Extend it to get ray OA
5.With O as the centre, draw an arc with suitable radius that cuts OB. Name the point of intersection as P

• A. 3,5,2,4,1
• B. 3,5,4,2,1
• C. 3,5,2,1,4
• D. 3,2,5,4,1

Answer 1

The correct option is C 3,5,2,1,4

Steps for the construction of $\angle AOB={120}^{\circ }$ is given below.
