X(2238)
(X(2)-ISOCONJUGATE OF X(741))


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            a/f(a,b,c) : b/f(b,c,a) : c/f(c,a,b), where f(a,b,c) is as in X(741)
Barycentrics    a2/f(a,b,c) : b2/f(b,c,a): c2/f(c,a,b)

X(2238) lies on these lines:
1,1573    2,6    8,2176    9,43    10,213    32,1009    37,42    44,513    218,442    220,1834    238,1914    239,350    291,1757    294,857    405,2271    429,607    748,2280    800,1713    860,1783    862,2201    978,2275    1107,1193    1778,2305

X(2238) = X(I)-Ceva conjugate conjugate of X(J) for these I,J: 98,55    660,512    666,523    1929,1962    2665,2667
X(2238) = cevapoint of X(1757) and X(2664)
X(2238) = crosspoint of X(I) and X(J) for these I,J: 52,2107    238,239    660,1016
X(2238) = crosssum of X(I) and X(J) for these I,J: 1,2238    81,1931    86,2669    291,292    659,1015    741,2311
