Question

If there is exactly one point common to a line AB and a circle, then the line AB can be

• A. A secant
• B. A tangent to the circle
• C. Sometimes a secant and sometimes a tangent
• D. A chord of the circle

Answer 1

The correct option is B A tangent to the circle

A tangent to the circle touches the circle at exactly one point. Thus, if line AB touches the circle at exactly one point, then AB can be the tangent to the circle.


Hence, the correct answer is option b.
