Menelaus' Theorem: For ABC , let D , E and F be menelaus points on BC , AC and AB respectively. The points D , E and F are collinear AFFBBDDCCEEA=1. Proof: Let D , E and F be menelaus points on BC , AC and AB respectively. : Let D , E and F be collinear. Case 1: The transversal made by the line through D , E and F goes through the interior of ABC . Let lBC through A , and let DEl=P
