Chord Length Using Perpendicular Distance from the Centre of the circle: \(C_\\ = 2 \times 5.Therefore, the two basic formulas for finding the length of the chord of a circle are as follows Thus using Pythagoras theorem, we may find the length of the chord CD easily. For example, the length of a chord can be used to find the circumference of a circle. It is due to the fact that perpendicular drawn from centre O on chord CD will be the bisector of CD. Chords can be used to solve problems in geometry. We may also calculate the chord length if we know both the radius and the length of the right bisector. We may determine the length of the chord from the length of the radius and the angle made by the lines connecting the circle’s centre to the two ends of the chord CD. chords that are equal or different in length and the center of a circle and use the properties of the chords in congruent circles to solve problems. The term is often used to describe a line segment whose ends lie on a circle. the longest chord, ‘OE’ will be the radius of the circle and line CD represents a chord of the circle, whereas curve CD will be the arc. Chord Download Wolfram Notebook In plane geometry, a chord is the line segment joining two points on a curve. ![]() ![]() In the given circle having ‘O’ as the centre, AB represents the diameter of the circle i.e. ![]() The same two points are connected by the curve in the form of the corresponding arc in the circle. 3 Solved Examples for Chord Length Formula What is a Chord in a Circle?Ī chord is the line segment in a circle, which connects any two points on the circumference of the circle.
