Click here to access the list of all triangle centers.

Interactive Applet

You can move the points A, B and C (click on the point and drag it).
Press the keys “+” and “−” to zoom in or zoom out the visualization window and use the arrow keys to translate it.

You can also construct all centers related with this one (as described in ETC) using the “Run Macro Tool”. To do this, click on the icon Run Macro Tool, select the center name from the list and, then, click on the vertices A, B and C successively.

The JRE (Java Runtime Environment) is not enabled in your browser!

Download all construction files and macros: (10.1 Mb).
This applet was built with the free and multiplatform dynamic geometry software C.a.R..

Information from Kimberling's Encyclopedia of Triangle Centers

Trilinears           f(a,b,c) : f(b,c,a) : f(c,a,b), where f(a,b,c) = bc(b2 - c2)(b4 + c4 - a2b2 - a2c2)       (M. Iliev, 5/13/07)

Barycentrics    af(a,b,c) : bf(b,c,a) : cf(c,a,b)

X(2799) lies on these lines:
2,1637    30,511    39,2507    98,1297    99,112    114,132    115,127    287,2395    620,2492    671,1494    850,2525    2514,2531

X(2799) = isogonal conjugate of X(2715)
X(2799) = X(I)-Ceva conjugate of X(J) for these I,J: 99,114    290,125    325,868    805,626    877,511    1916,115
