## X(319) (ISOTOMIC CONJUGATE OF X(79))

 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 + 2 cos A)/a2 : (1 + 2 cos B)/b2 : (1 + 2 cos C)/c2
Barycentrics    (1 + 2 cos A)/a : (1 + 2 cos B)/b : (1 + 2 cos C)/c

X(319) lies on these lines: 2,1100    7,8    10,86    80,313    141,239    171,757    200,326    261,502    298,1082    299,559    306,333    307,664    317,318    321,1029    344,391    524,594

X(319) = reflection of X(894) in X(594)
X(319) = isotomic conjugate of X(79)
X(319) = anticomplement of X(1100)
