Journal for Geometry and Graphics 11 (2007), No. 1, 039--044 Copyright Heldermann Verlag 2007 A Unified Proof of Ceva and Menelaus' Theorems Using Projective Geometry Julio Benítez Dep. de Matematica Aplicada, Universidad Politecnica, Valencia, Spain jbenitez@mat.upv.es We prove that the well known Ceva and Menelaus' theorems are both particular cases of a single theorem of projective geometry. Keywords: Ceva's theorem, Menelaus' theorem, projective geometry. MSC: 51M04; 51N15 [ Fulltext-pdf (106 KB)] for subscribers only. |
