X(908)
(POINT ACUBENS)


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..

Trilinears            f(a,b,c) : f(b,c,a) : f(c,a,b),
                                    where f(a,b,c) = [(wb + vc)/a - v - w]/a, u : v : w = X(3)
Barycentrics    af(a,b,c) : bf(b,c,a) : cf(c,a,b)

X(908) lies on these lines:
1,998    2,7    4,78    5,72    8,946    10,994    11,518    12,960    80,519    92,264    100,516    119,517    153,515    214,535    224,1079    377,936    392,495    514,661

X(908) = reflection of X(1512) in X(119)
X(908) = isogonal conjugate of X(909)
X(908) = crosssum of X(41) and X(902)
X(908) = crossdifference of any two points on line X(31)X(663)
