(SR(X(100), X(103)))


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: tc.zip (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            f(a,b,c) : f(b,c,a) : f(c,a,b), where f(a,b,c) is as given just before X(2677) using P = X(100), U = X(103)
Barycentrics    af(a,b,c) : bf(b,c,a) : cf(c,a,b)

X(2717) lies on the circumcircle and these lines:
3,1308    36,934    40,2742    55,2222    57,2720    92,1309    100,516    101,517    103,513    104,514    108,2078    109,1155    165,901    573,813    650,2291    1292,2077

X(2717) = reflection of X(1308) in X(3)
X(2717) = isogonal conjugate of X(2801)
X(2717) = cevapoint of X(55) and X(2246)
