How to Calculate Chord Length

A chord of a circle is a line segment with its endpoints on the circle. The diameter of a circle is a chord that intersects the center of the circle. A line that contains a chord of a circle is known as a secant of that circle. It is possible to calculate a chord's length when the circle's radius and the central angle of the chord are given. We can also calculate a chord's length when we know the circle's radius and distance of the chord to the center of the circle.
