**Answer: **(d) A straight line can meet a circle at one point only.

## Sol:

A straight be can meet a circle at one point only

This statement is not true because a straight line that is not a tangent but a secant cuts the circle at two points.

(a) A tangent to a circle intersects the circle exactly at one point.

(b) The point common to the circle and its tangent is called the point of contact.

(c) The tangent at any point of a circle is perpendicular to the radius of the circle through the point of contact.
