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(1220)
Barycentrics    a2/f(a,b,c) : b2/f(b,c,a): c2/f(c,a,b)

X(2300) lies on these lines:
1,6    10,992    19,1572    31,184    32,48    36,2305    39,71    81,261    110,1169    239,314    284,893    394,2221    572,595    573,995    579,2275    573,995    579,2275    849,1333    869,2209    1015,2260    1185,2280    1193,1682    1201,1400    1918,1964    2174,2220

X(2300) = X(I)-Ceva conjugate of X(J) for these I,J: 6,2092    110,667
X(2300) = crosspoint of X(I) and X(J) for these I,J: 6,1333    31,904    56,81
X(2300) = crosssum of X(I) and X(J) for these I,J: 2,321    8,37    75,1909    1791,2298
