Question

A circle of radius r has a center O. What is first step to construct a tangent from a generic point P which is at a distance r from O?

Options

• With P as center and radius > r, draw a circle and then join OP.

• With P as center and radius < r, draw a circle and then join OP.

• With P as center and radius = r, draw a circle and then join OP.

• Join OP.

Answer 1

Join OP.

Explanation:-

P is a point on the circle. We know that only one tangent can be drawn and it is perpendicular to the line joining the centre of the circle O and the point of contact P.

So our first step would be to join OP.
