Question

A line with end points A and B and a circle with centre O lie on a plane as shown. Is AB the chord of the circle with centre O?

• A. True
• B. False

Answer 1

The correct option is B

False

The chord of the circle is the line joining two points on the circumference of the circle.

In the above figure, the end points of the line, i.e., A and B are not points on the circumference of the circle. Hence, AB is not a chord of the circle.
Since the line AB cuts the circle at two distinct points, it is a secant of the circle.
