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) is as given just before X(2979), using U = X(21)
Barycentrics    af(a,b,c) : bf(b,c,a) : cf(c,a,b)

X(2982) lies on these lines:
1,201    2,219    6,278    28,65    48,57    55,955    81,1214    222,279    274,1231    1002,1617    1396,1409    1630,1730

X(2282) = cevapoint of X(I) and X(J) for these I,J: 6,65    56,1409    57,2003
X(2982) = X(I)-cross conjugate of X(J) for these I,J: 6,1175    647,108    2259,943    2605,934
X(2982) = crosssum of X(1) and X(2954)
