WebTwo chords are equal in length if they are equidistant from the center of a circle. For example, chord AB is equal to chord CD if PQ = QR. How to Find the Chord of a Circle? There are two formulas to find the length of a chord. Each formula is used depending on the information provided. WebThe angle between a chord and the tangent at one of its endpoints is equal to one half the angle subtended at the centre of the circle, on the opposite side of the chord (tangent chord angle). If the angle subtended by the chord at the centre is 90 ° , then ℓ = r √2 , where ℓ is the length of the chord, and r is the radius of the circle.
