## X(2963) (BARYCENTRIC PRODUCT X(17)*X(18))

 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) = sin A csc(A + π/6) csc(A - π/6)
Barycentrics    (sin A)f(A,B,C) : (sin B)f(B,C,A) : (sin C)f(C,A,B)

X(2963) lies on these lines:
2,1225    5,2965    6,17    25,2934    37,2962    50,252    53,1487    93,393    111,930    141,2987    216,1989    230,251    566,2165    588,590    589,615    1879,2937

X(2963) = isogonal conjugate of X(1994)
X(2963) = cevapoint of X(590) and X(615)
X(2963) = X(570)-cross conjugate of X(6)
X(2963) = crosssum of X(I) and X(J) for these I,J: 6,195    49,2965
