WebNov 27, 2015 · Ceva's Theorem Giovanni Ceva (1648-1734) proved a theorem bearing his name that is seldom mentioned in Elementary Geometry courses. It's a regrettable fact because not only it unifies several other more fortunate statements but its proof is actually as simple as that of the less general theorems. WebJul 5, 2024 · Cevian (from the 17th century Italian mathematician Giovanni Ceva (cheh’va)) is a line of a triangle from a vertex to a (non-vertex) point of the line of the side opposite. As examples, the medians of a triangle, its angle bisectors, and its altitudes are all Cevians, but they need not be anything so special.

WebThe Menelaus theorem gives a necessary and sufficient condition for three points - one on each side of a triangle - to lie on a transversal. What is a Cevian in one triangle is a transversal in another. For example, the Cevian BE serves as a transversal in ΔADC while CF is a transversal in ΔADB.

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.
