KnowraPappus's hexagon theoremLinked fromLinked fromThe 9 pages that link to Pappus's hexagon theorem, each with the reason it gives.All 9Broader topic 1Related 5Compared with 3Ceva's theoremRelated: This ancient incidence theorem illustrates the classical geometry tradition in which Ceva's result was developed.Complete quadrilateralRelated: Classical treatments relate its incidence structure to complete quadrilaterals.Brianchon's theoremCompared with: It offers another hexagon incidence theorem, but does not require tangency to a conic.Miquel's theoremRelated: Both results reveal unexpected incidence consequences from a small arrangement of lines.Pappus of AlexandriaBroader topic: This later theorem bears Pappus’s name, though it is not securely attributable to him.Menelaus's theoremRelated: It is another classical theorem where incidence forces collinearity.Desargues's theoremRelated: It is a related incidence theorem with stronger algebraic implications for projective planes.Six circles theoremCompared with: Pappus also uses a hexagonal arrangement, but concerns points on lines and a line conclusion.Thomsen's theoremCompared with: It is another incidence theorem with a six-point configuration, but its conclusion is collinearity.
