- Holditchs theorem - Wikipedia
Holditch's theorem In plane geometry, Holditch's theorem states that if a chord of fixed length is allowed to rotate inside 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 enclosed area is less than that of the original curve by
- Holditchs Theorem - from Wolfram MathWorld
Provided certain conditions are met, the area between C and C^' is given by pipq, as first shown by Holditch in 1858 The Holditch curve for a circle of radius R is another circle which, from the theorem, has radius r=sqrt (R^2-pq)

In this paper we present a certain modification of the Holditch construction This construction allows to consider a geometric family of pairs of ring domains It is proved that the ratio of areas of ring domains of each pair belonging to this family is constant

In order to make explicit the assumptions Holditch apparently made, and to clarify the conditions under which his theorem holds, we wish to carefully restate the theorem

Obtaining the equation of the Holditch curve is usually difficult, but here are two simple cases:
- HOLDITCH’S ENVELOPE - mathres. org
As Holditch, we assume to start with a convex simple curve that bounds a compact convex region Furthermore, the curve is said to be Ck-regular on an open interval if it is k times continuously differentiable with nonvanishing derivative on that interval
