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            a/f(a,b,c) : b/f(b,c,a) : c/f(c,a,b), where f(a,b,c) is as in X(1002)
Barycentrics    a2/f(a,b,c) : b2/f(b,c,a): c2/f(c,a,b)

X(2280) lies on these lines:
1,41    3,1475    6,31    9,1174    32,1468    34,2332    37,2348    48,354    57,77    145,2329    165,572    213,2241    218,1334    380,2285    748,2238    985,1002    999,1055    1155,2278    1185,2300    1193,2271    1212,1802    1400,1617    1405,2078    1829,1973    1851,2201    2242,2251    2272,2317    2291,2364

X(2280) = X(985)-Ceva conjugate of X(31)
