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            f(a,b,c) : f(b,c,a) : f(c,a,b), where f(a,b,c) = a(b - c)2(b + c - a)3
Barycentrics    af(a,b,c) : bf(b,c,a) : cf(c,a,b)

X(3022) lies on the incircle and these lines:
1,1362    11,116    12,118    33,181    56,103    65,1360    101,2291    150,497    152,388    926,2170    928,1364    950,2784    1282,1697    1317,2801    1359,2823    1361,2099    1397,2192    1682,3033    2772,3028    2774,3024    2786,3023    2809,3021

X(3022) = reflection of X(I) in X(J) for these I,J: 8,3041    1362,1
X(3022) = X(I)-Ceva conjugate of X(J) for these I,J: 7,650    55,657
X(3022) = crosspoint of X(I) and X(J) for these I,J: 7,650    55,657    607,663
X(3022) = crosssum of X(I) and X(J) for these I,J: 7,658    55,651    100,144    279,934    348,664
