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            a/f(a,b,c) : b/f(b,c,a) : c/f(c,a,b), where f(a,b,c) is as in X(983)
Barycentrics    a2/f(a,b,c) : b2/f(b,c,a): c2/f(c,a,b)

X(2275) lies on these lines:
1,39    2,330    3,1914    6,41    8,1575    9,1050    32,36    34,232    35,574    46,1572    57,893    65,2186    87,256    194,350    213,995    216,1038    579,2300    614,1194    672,1201    978,2238    1149,1334    1449,2092    1573,1698

X(2275) = crosspoint of X(I) and X(J) for these I,J: 57,87    58,274
X(2275) = crosssum of X(I) and X(J) for these I,J: 6,1376    9,43    10,213
