Answer:

A chord of a circle is a straight line segment whose endpoints both lie on the circle. The infinite line extension of a chord is a secant line, or just secant. More generally, a chord is a line segment joining two points on any curve, for instance, an ellipse.

The formula for the chord length is:

2rsin(theta/2)

where r is the radius of the circle and theta is the angle from the centre of the circle to the two points of the chord.
