In Euclidean geometry, the isodynamic points of a triangle are points associated with the triangle, with the properties that an inversion centered at one of these points transforms the given triangle into an equilateral triangle, and that the distances from the isodynamic point to the triangle vertices are inversely proportional to the opposite side lengths of the triangle. Triangles that are similar to each other have isodynamic points in corresponding locations in the plane, so the isodynamic points are triangle centers, and unlike other triangle centers the isodynamic points are also invariant under Möbius transformations. A triangle that is itself equilateral has a unique isodynamic point, at its centroid(as well as its orthocenter, its incenter, and its circumcenter, which are concurr

  • Die beiden isodynamischen Punkte gehören zu denausgezeichneten Punkten eines Dreiecks. Gegeben sei ein Dreieck ABC mit den Halbierenden seiner Innen- und Außenwinkel.Ua sei der Schnittpunkt der Winkelhalbierenden von mit derGeraden BC, Va der Schnittpunkt der entsprechenden Außenwinkelhalbierenden mitBC. Entsprechend seien die Punkte Ub und Vb (jeweils auf CA)sowie Uc und Vc (jeweils auf AB) definiert. Dann haben die drei Kreisemit den Durchmessern |Ua Va|, |Ub Vb| und|Uc Vc| zwei Punkte S und S' gemeinsam. S wird als1. isodynamischer Punkt bezeichnet (Kimberling-Nummer ), S' als 2. isodynamischer Punkt (Kimberling-Nummer ). (de)
  • En géométrie euclidienne, les points isodynamiques du triangle sont des points associés à un triangle, telles qu'une inversion centrée en un de ces points transforme le triangle en un triangle équilatéral, et que les distances entre le point isodynamique aux sommets du triangle sont inversement proportionnelles aux longueurs des côtés opposés du triangle. Ce sont des centres du triangle, invariants par transformation de Möbius. Un triangle équilatéral n'a qu'un point isodynamique, en son centre de gravité ; tous les autres en ont deux distincts. Les points isodynamiques ont d'abord été étudiés par Joseph Neuberg. (fr)
  • De isodynamische punten van een driehoek zijn de snijpunten van de drie cirkels van Apollonius van die driehoek.De isodynamische punten zijn isogonaal verwant met het punt van Fermat en tweede isogone centrum en hebben Kimberlingnummers X(15) en X(16). (nl)
  • Точки Аполлонія (іноді ізодинамічні центри) — дві такі точки, відстані від яких до вершин трикутника обернено пропорційні сторонам, протилежним до цих вершин. (uk)
  • Точки Аполлония (иногда изодинамические центры) — две такие точки, расстояние от которых до вершин треугольника обратно пропорциональны сторонам, которые противолежат этим вершинам. (ru)
