anticomplementary การใช้

Conversely the Nagel point of any triangle is the incenter of its anticomplementary triangle.
The name " anticomplementary triangle " corresponds to the fact that its vertices are the anticomplements of the vertices A, B, C of the reference triangle.
The Lucas cubic passes through the centroid, orthocenter, Gergonne point, Nagel point, de Longchamps point, other triangle centers, the vertices of the anticomplementary triangle, and the foci of the Steiner circumellipse.
For property 6, it was already established that the perpendicular bisectors of the sides of the anticomplementary triangle all pass through the point " H "; since that side is parallel to a side of the reference triangle, these perpendicular bisectors are also the altitudes of the reference triangle.
