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..

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(1255)
Barycentrics    a2/f(a,b,c) : b2/f(b,c,a): c2/f(c,a,b)

X(2308) lies on these lines:
6,31    36,58    38,1386    44,756    56,1392    81,238    110,1171    171,899    184,1475    222,1471    612,1743    748,940    968,1449    999,1201    1042,1451    1100,1962    1197,1977    1397,1400    1402,1404    1405,1460    1458,2003    2194,2260    2203,2354    2258,2364

X(2308) = isogonal conjugate of X(1268)
X(2308) = X(110)-Ceva conjugate of X(649)
X(2308) = crosspoint of X(I) and X(J) for these I,J: 1,2160    6,58    1125,1839
X(2308) = crosssum of X(I) and X(J) for these I,J: 2,10    1126,1796
