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            1/f(a,b,c) : 1/f(b,c,a) : 1/f(c,a,b), where f(a,b,c) is as at X(2687)
Barycentrics    a/f(a,b,c) : b/f(b,c,a) : c/f(c,a,b)

X(2771) lies on these lines:
1,399    3,191    11,113    21,104    30,511    36,1749    65,79    72,74    78,2932    109,1807    119,125    146,149    153,355    214,960    500,2292    946,1484    1464,1725    1829,1986

X(2771) = isogonal conjugate of X(2687)
X(2771) = X(2694)-Ceva conjugate of X(3)
