Finding chord length
WebMay 18, 2024 · How to Calculate the Length of a Chord Produced by an Angle. The length of a chord can be calculated using the Cosine Rule. For the triangle XYZ in the diagram below, the side opposite the angle θ is the chord with length c. From the Cosine Rule: c 2 = R 2 + R 2-2RRcos θ Simplifying: c 2 = R 2 + R 2-2R 2 cos θ or c 2 = 2R 2 (1 - cos θ) Let R be the radius of the arc which forms part of the perimeter of the segment, θ the central angle subtending the arc in radians, c the chord length, s the arc length, h the sagitta (height) of the segment, d the apothem of the segment, and a the area of the segment. Usually, chord length and height are given or measured, and sometimes the arc length as part of the perimeter, and the unknowns are area and sometimes arc length. These can't be calculate…
