Question

There is a circle with centre O. P is a point from where only one tangent can be drawn to this circle. What can we say about P?

• A. P is outside the circle.
• B. P is inside the circle.
• C. P is on the circle.
• D. O and P are co-incident points.

Answer 1

The correct option is C

P is on the circle.

Since only one tangent can be drawn, this point P should be present on the circle.

Any point on the circle is at a distance equal to the radius of the circle. So OP is equal to the radius of the circle.
