Question

To draw a perpendicular from a given point P on line XY,name the point where the needle of the compass should be placed first

Answer 1

Answer: To draw a perpendicular from a given point P on line XY, the needle of the compass should be placed first at the point P.

Explanation:

• First place the needle on the point P.

• Then draw an arc that intersection the line XY in two points.

• Now place the needle on one of the intersections and draw a small arc downwards.

• Do the same with the other intersection.

• You will see that both the smaller arcs are meeting each other at some point.

• Now join the point of intersection of the two arcs with the point P.

• You will get the perpendicular line of XY.
