## X(2110) (POINT KEPLER III)

 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 , select the center name from the list and, then, click on the vertices A, B and C successively.

Trilinears            f(a,b,c) : f(b,c,a) : f(c,a,b), where
f(a,b,c) = a[(b2 + bc + c2)a3 - (b + c)(b2 + c2)a2 - bc(b2 - bc + c2)a + b2c2(b + c)]
Barycentrics    af(a,b,c) : bf(b,c,a) : cf(c,a,b)

X(2110) lies on these lines:
2,11    6,292    31,1979    238,2111    365,2119    672,2117    1185,1977    1423,1740    1931,2113

X(2110) = X(I)-Ceva conjugate of X(J) for these I,J: 238,6    2223,55
