### What is Meant by the Chord of a Circle?

In Mathematics, a circle is a closed two-dimensional figure, and all the points on the surface of the circle are equidistant from the centre point. The distance between the surface of the circle and the centre point is called the radius. The chord of a circle is defined as the line segment that joins two points on the circle’s circumference. We can say that the diameter is the longest chord of a circle. The diameter is a line segment that joins two points on the circumference of a circle which passes through the centre of the circle. The formula to calculate the length of a chord is given by:

If the radius and the perpendicular distance from the centre of a circle are given, then the length of a chord is:

Chord Length = 2 × √(r2 − d2)
