WebFigure 1 Two chords intersecting inside a circle. Theorem 83: If two chords intersect inside a circle, then the product of the segments of one chord equals the product of the segments of the other chord. Example … The intersecting chords theorem or just the chord theorem is a statement in elementary geometry that describes a relation of the four line segments created by two intersecting chords within a circle. It states that the products of the lengths of the line segments on each chord are equal. It is Proposition 35 of Book 3 of Euclid's Elements.

So we already know 2 sides for this triangle and just need to solve for L and double it to get the second chord length. r^2=a^2+L^2. L^2=r^2-a^2 = 35.23^2-17^2. L= sqrt (35.23^2-17^2) L=30.85. Just double that to get the length of the second cord. euston station london underground
