## X(519) (ISOGONAL CONJUGATE OF X(106))

 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.

As the isogonal conjugate of a point on the circumcircle, X(519) lies on the line at infinity.

X(519) lies on these lines: 1,2    6,996    9,1000    30,511    36,100    40,376    55,956    58,1043    65,553    72,950    80,908    210,392    238,765    320,668    355,381    447,648    594,1100    672,1018    751,984

X(519) = isogonal conjugate of X(106)
X(519) = isotomic conjugate of X(903)
X(519) = complementary conjugate of X(121)
X(519) = X(I)-Ceva conjugate of X(J) for these (I,J): (4,121), (80,10)
X(519) = crosssum of X(I) and X(J) for these (I,J): (6,902), (56,1457)
X(519) = crossdifference of any two points on line X(6)X(649)
X(519) = X(I)-Hirst inverse of X(J) for these (I,J): (513,537), (514,545)
