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(79)
Barycentrics    a2/f(a,b,c) : b2/f(b,c,a): c2/f(c,a,b)

X(2174) lies on these lines:
1,584    6,41    9,2278    36,583    37,101    44,572    45,2268    50,1399    53,2202    55,2164    65,2160    71,1030    199,209    213,1333    220,2289    228,2194    560,869    594,2329    662,894    872,922    910,1630    1409,1415    1964,2210    2171,2173    2176,2304    2220,2251    2264,2302

X(2174) = X(I)-Ceva conjugate of X(J) for these I,J: 80,2361    1126,31    2003,1399    2259,6
X(2174) = crosspoint of X(35) and X(2003)
