## X(2883) (COMPLEMENTARY CONJUGATE OF X(4))

 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) is as described just before X(2883)
Barycentrics    af(a,b,c) : bf(b,c,a) : cf(c,a,b)

X(2883) lies on these lines:
2,64    3,1661    4,6    20,154    30,156    51,1906    184,1885    185,235    221,497    388,2192    389,1596    417,1624    459,1192    468,1204    496,942    550,1511    1593,1619

X(2883) = midpoint of X(4) and X(1498)
X(2883) = complement of X(64)
X(2883) = complementary conjugate of X(4)
X(2883) = X(2)-Ceva conjugate of X(800)
