Question

Steps for the construction of $\angle ABC={60}^{\circ }$ are given below. Choose the correct order.

1. With O as the centre and with any suitable radius draw an arc using compasses, which cuts the ray OA . Name the point of intersection as B.
2. Draw a ray OA using a scale and a pencil.
3. Join OC using a scale and a pencil. Extend it to get ray OD.
4. With B as the centre and with the same radius as in step2, draw an arc cutting the previous arc. Name the point of intersection as C.

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