## X(2590) (X(2)-ISOCONJUGATE OF X(1381))

 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            a/f(a,b,c) : b/f(b,c,a) : c/f(c,a,b), where f(a,b,c) is as at X(1381)
Barycentrics    a2/f(a,b,c) : b2/f(b,c,a) : c2/f(c,a,b)

X(2590) lies on these lines: 44,513    101,1381    1382,2291    2170,2446

X(2590) = X(I)-Ceva conjugate of X(J) for these I,J: 57,2446    101,2591    1381,55
X(2590) = X(2170)-cross conjugate of X(2591)
X(2590) = crosspoint of X(57) and X(1381)
X(2590) = crosssum of X(1) and X(2590)
