## X(88) (ISOGONAL CONJUGATE OF X(44))

 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.

This applet was built with the free and multiplatform dynamic geometry software C.a.R..

Trilinears           1/(b + c - 2a) : 1/(c + a - 2b) : 1/(a + b - 2c)
Barycentrics    a/(b + c - 2a) : b/(c + a - 2b) : c/(a + b - 2c)

X(88) lies on these lines: 1,100    2,45    6,89    28,162    44,679    57,651    81,662    105,901    274,799    278,653    279,658    291,660

X(88) = isogonal conjugate of X(44)
X(88) = cevapoint of X(I) and X(J) for these (I,J): (1,44), (6,36)
X(88) = X(I)-cross conjugate of X(J) for these (I,J): (44,1), (517,7)
X(88) = X(I)-aleph conjugate of X(J) for these (I,J): (88,1), (679,88), (903,63), (1022,1052)
X(88) = X(333)-beth conjugate of X(190)
