## X(1393) (X(5)-BETH CONJUGATE OF X(5))

 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.

 The JRE (Java Runtime Environment) is not enabled in your browser!

Download all construction files and macros: tc.zip (10.1 Mb).
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) = (1 - cos A)u(a,b,c), where u : v : w = X(5)
Barycentrics    af(a,b,c) : bf(b,c,a) : cf(c,a,b)

X(1393) lies on these lines:
1,1389    2,201    11,774    12,38    31,1454    46,602    56,244    65,1193    73,942    225,1210    227,354    278,1148    388,982    595,1421

X(1393) = crosspoint of X(57) and X(273)
X(1393) = crosssum of X(9) and X(212)
