Brianchon Charles Julien Brianchon. Born 19 Dec 1783 in Sèvres, France Died 29 April 1864in Versailles, France. CharlesJulien Brianchon's background is not known. http://www-gap.dcs.st-and.ac.uk/~history/Mathematicians/Brianchon.html
Extractions: Charles-Julien Brianchon 's background is not known. We do not know anything of his primary or secondary education and the first definite educational record that exits is his entry into the Ecole Polytechnique in 1804 at the age of eighteen. At the Ecole Polytechnique in Paris, Brianchon studied under Monge . In fact he published his first paper in the Journal de l'Ecole Polytechnique while still a student. In that paper Brianchon rediscovered Pascal 's Magic Hexagon. He showed that in any hexagon formed of six tangents to a conic , the three diagonals meet at a point. This result is often called Brianchon's Theorem and it is the result for which he is best known. In fact this theorem is simply the dual of Pascal 's theorem which was proved in 1639:- If all the vertices of a hexagon lie on a conic, and if the opposite sides intersect, then the points of intersection lie on a line. In [1] Greitzer points out that Pascal recognised that his theorem was projective in nature so it is surprising that it took 167 years before someone realised that its dual, which is Brianchon's Theorem, would also be true.

Extractions: In onderstaande paragrafen behandelen we enkele eigenschappen van n-hoeken (n = 3, 4, 5) in samenhang met de cirkels van Euler en het concyclisch zijn van bijzondere punten, alsmede het verband tussen het punt van Euler van een vierhoek en een orthogonale hyperbool door de vierhoekpunten (naar Leonard Euler , 1707-1783, Zwitserland). Definitie De Euler-cirkel van een koorde van een cirkel met straal R is de cirkel met straal R/2 die als middelpunt het midden van de koorde heeft ( zie figuur 1 figuur 1 figuur 2 In figuur 2 zijn de Euler-cirkels van de zijden van driehoek ABC getekend; de zijden zijn dus opgevat als koorden van de omcirkel van ABC.
