A Theorem of Isoperimetric Loops

Published online by Cambridge University Press:  03 November 2016

Extract

The following note is intended to draw attention to a curious relation which I arrived at, some years ago, between the lengths of the common tangents of two intersecting ellipses, and the lengths of the arcs between their points of contact.

The property proved may be regarded as an extension of Graves’ Theorem [SALMON; Art. 399] and is deduced from that theorem in conjunction with a lemma proved in this note.
