Holditch's theorem

Holditch's theorem

In plane geometry, Holditch's theorem states that if a chord of fixed length is allowed to rotate around a convex closed curve, then the locus of a point on the chord a distance "p" from one end and a distance "q" from the other is a closed curve whose area is less than that of the original curve by pi pq.
