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!

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(306)
Barycentrics    a2/f(a,b,c) : b2/f(b,c,a): c2/f(c,a,b)

X(2203) lies on these lines:
6,25    19,2214    28,60    31,1932    58,1473    112,739    209,692    468,1211    604,1395    608,1397    1172,1824    1396,1462    1398,1407    2308,2354

X(2203) = X(I)-Ceva conjugate of X(J) for these I,J: 28,1333    1474,2204
X(2203) = cevapoint of X(I) and X(J) for these I,J: 1395,1397    1973,1974
X(2203) = X(I)-cross conjugate of X(J) for these I,J: 1397,2206    1973,1474
