A chord in a circle is defined as the line segment joining any two points on the circumference of the circle. It should be noted that the diameter is the longest chord of a circle, which passes through the center of the circle. The perpendicular to a chord, drawn from the center of the circle, bisects the chord. Chords are equidistant from the center if and only if their lengths are equal. Equal chords are subtended by equal angles from the center of the circle
. For example, in the given circle with 'O' as the center, AB represents the diameter of the circle (longest chord), 'OE' denotes the radius of the circle, and CD represents a chord of the circle
