Menelaus's theorem, named for Menelaus of Alexandria, is a proposition about triangles in plane geometry. Suppose we have a triangle ABC, and a transversal line that crosses BC, AC, and AB at points D, E, and F respectively, with D, E, and F distinct from A, B, and C. A weak version of the theorem states that where AB is taken to be the ordinary length of segment AB: a positive value. Webチェバの定理（ちぇばのていり、Ceva's theorem）とは、平面幾何学の定理の1つである。定理の名は、1678年にジョバンニ・チェバがDe lineis rectisを出版して証明を発表した[1]のにちなむ。今判明している初出は、11世紀のサラゴサの王で数学者 Yusuf al-Mu'taman ibn Hud（英語版）の数学全書 Kitab al-lstikmalである[2]。定理[編集] 三角形ABCにおいて …

WebCeva's theorem is essentially the counterpart of this theorem and can be used to prove three lines are concurrent at a single point. Both theorems possess similar structures and are widely applicable in various geometry … In Euclidean geometry, Ceva's theorem is a theorem about triangles. Given a triangle △ABC, let the lines AO, BO, CO be drawn from the vertices to a common point O (not on one of the sides of △ABC), to meet opposite sides at D, E, F respectively. (The segments AD, BE, CF are known as cevians.) Then, using signed … See more Several proofs of the theorem have been given. Two proofs are given in the following.
