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..

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(1170)
Barycentrics    a2/f(a,b,c) : b2/f(b,c,a): c2/f(c,a,b)

X(2293) lies on these lines:
1,7    3,1471    6,31    9,2340    33,1839    37,2310    48,1486    73,1456    200,391    284,2195    354,1418    500,1066    608,2356    651,2346    692,2317    756,1864    1001,1818    1201,1279    1400,2223

X(2293) = X(I)-Ceva conjugate of X(J) for these I,J: 1,354    354,1475    651,657    1292,649
X(2293) = crosspoint of X(I) and X(J) for these I,J: 1,55    6,2191    354,1212
X(2293) = crosssum of X(I) and X(J) for these I,J: 1,7    1170,2346
