A line with endpoints A and B and a circle with centre O lying on a plane as shown. Is AB the chord of the circle with centre O?
False
The chord of the circle is the line joining two points on the circumference of the circle.
In the above figure, the endpoints 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 in two distinct points, it is a secant of the circle
