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(2745)
Barycentrics    a/f(a,b,c) : b/f(b,c,a) : c/f(c,a,b)

X(2829) lies on these lines:
1,1537    3,119    4,11    20,100    30,511    36,1532    40,1145    46,80    355,1158    944,1317    946,1387    962,1320    990,998    1012,1478    1155,1512    1319,1519    1455,1785    1862,1885

X(2829) = isogonal conjugate of X(2745)
