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!

This applet was built with the free and multiplatform dynamic geometry software C.a.R..

Information from Kimberling's Encyclopedia of Triangle Centers

Trilinears           3a + b + c : 3b + c + a : 3c + a + b
Barycentrics    a(3a + b + c) : b(3b + c + a) : c(3c + a + b)

X(1449) lies on these lines:
1,6    7,1419    32,988    34,1172    40,572    43,1051    57,77    65,380    87,1045    198,999    579    1475    610,942    894,1278    966,1125    1400,1420    1442,1445

X(1449) = {X(1),X(6)}-harmonic conjugate of X(9)
X(1449) = X(391)-beth conjugate of X(391)
