Question

Arrange the steps of construction of ${60}^{\circ }$ angle in the correct sequential order.
1. Draw a line.
2. Place the Protractor on the line. Place the mid - point of the protractor at point one edge of the line.
3. On the line starting from the right at $0^{\circ }$ mark a point at the ${60}^{\circ }$ division using a pencil.
4. Remove the protractor and draw a line to the marked point.
5. The angle formed is ${60}^{\circ }.$

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

Answer 1

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

1. Draw a line segment PA.

2. Place the protractor on the line segment PA. Place the midpoint of the protractor at point P as shown in the figure.

3. On PA from the right start counting from $0^{\circ }$ in ascending order anti-clockwise direction and finally mark a point Q using a sharp pencil at the point showing ${60}^{\circ }$ on the semi-circular edge of the protractor.
4. Remove the protractor and join PQ.
5. Then we find that $\angle APQ={60}^{\circ }.$
