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(321)
Barycentrics    a2/f(a,b,c) : b2/f(b,c,a): c2/f(c,a,b)

X(2206) lies on these lines:
6,199    21,987    31,48    32,184    36,58    42,284    81,982    99,697    110,727    604,1395    902,2328    909,2299    1106,1408    1201,2360    1412,1416    1437,1472    1780,1801    1922,2205    2204,2208

X(2206) = isogonal conjugate of X(313)
X(2206) = X(849)-Ceva conjugate of X(1333)
X(2206) = cevapoint of X(32) and X(560)
X(2206) = X(1397)-cross conjugate of X(2203)
X(2206) = crosspoint of X(I) and X(J) for these I,J: 58,1474    1333,1408
X(2206) = crosssum of X(I) and X(J) for these I,J: 2,1330    10,306
