What is the relationship between an arc and a chord?

An arc is a segment of a circle defined by two points on the circle, while a chord is a straight line connecting those two points. The chord divides the circle into two arcs, one larger and one smaller, depending on the positions of the endpoints. The length of the chord is related to the degree measure of the intercepted arc; as the angle increases, the chord length increases, and vice versa. Thus, arcs and chords are intrinsically linked through their geometric properties within a circle.
