In geometry, the Nagel point (named for Christian Heinrich von Nagel) is a triangle center, one of the points associated with a given triangle whose definition does not depend on the placement or scale of the triangle. It is the point of concurrency of all three of the triangle's splitters. Zobacz więcej Given a triangle △ABC, let TA, TB, TC be the extouch points in which the A-excircle meets line BC, the B-excircle meets line CA, and the C-excircle meets line AB, respectively. The lines ATA, BTB, CTC concur in … Zobacz więcej The un-normalized barycentric coordinates of the Nagel point are $${\displaystyle (s-a:s-b:s-c)}$$ where $${\displaystyle s={\tfrac {a+b+c}{2}}}$$ is the semi-perimeter of … Zobacz więcej • Mandart inellipse • Trisected perimeter point Zobacz więcej • Nagel Point from Cut-the-knot • Nagel Point, Clark Kimberling • Weisstein, Eric W. "Nagel Point". MathWorld. Zobacz więcej The Nagel point is the isotomic conjugate of the Gergonne point. The Nagel point, the centroid, and the incenter are collinear on a line called the Nagel line. The incenter is the Nagel point of the medial triangle; equivalently, the Nagel point is the incenter of the Zobacz więcej The trilinear coordinates of the Nagel point are as or, … Zobacz więcej The Nagel point is named after Christian Heinrich von Nagel, a nineteenth-century German mathematician, who wrote about it in 1836. … Zobacz więcej Witrynatriangle ABC, the Feuerbach point F is the point of tangency with the incircle. There exists a family of cevian circumcircles passing through the Feuerbach point. Most remarkable are the cevian circumcircles of the incenter and the Nagel point.1 In this note we give a geometric proof in the incenter case. Theorem.
