Holditch expressed the Holditch theorem in the article entitled ”Geometrical Theorem” in 1858. Holditch theorem is stated that ”If the end points of a chord, with constant length a+b, draw any closed curve, any point on this chord draw different closed curve. So, the area between these curves is always pab”, [5]. The most important ...

NettetThe deﬁnition of Holditch surface works to any curve, but we will focus later in closed curves in order to generalize Holditch’s theorem for space closed curves. Look at Fig. 2 to see some examples of Holditch surfaces for closed curves. Deﬁne φ(s,u) as the angle between t(s)andt(s+u). It is easy to show NettetTheorem 1.1 (Holditch’s Theorem) Let a chord with constant lengths of a+b of a closed convex curve α be divided by a point on it into two segments with and b as lengths. Let us move the end-points of the chord so that they will entirely trace the curve.
