## X(340) (ISOTOMIC CONJUGATE OF X(265))

 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           f(A,B,C) : f(B,C,A) : f(C,A,B), where
f(A,B,C) = sec A sin 3A csc3A

Barycentrics    g(A,B,C) : g(B,C,A) : g(C,A,B), where
g(A,B,C) = sec A sin 3A csc2A

X(340) lies on these lines: 4,69    67,290    95,140    250,325    297,524    298,470    299,471    447,540    458,599    520,850

X(340) = reflection of X(648) in X(297)
X(340) = isotomic conjugate of X(265)
X(340) = cevapoint of X(186) and X(323)
