## X(1776) (MIMOSA TRANSFORM OF X(1156))

 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..

 Information from Kimberling's Encyclopedia of Triangle Centers

Trilinears           f(a,b,c) : f(b,c,a) : f(c,a,b), where f(a,b,c) = - (cos A)/x + (cos B)/y + (cos C)/z,    x : y : z = X(1156)
Barycentrics    af(a,b,c) : bf(b,c,a) : cf(c,a,b)

X(1776) lies on these lines: 4,46    21,60    33,1707    63,497    109,1736    191,950    243,522    411,1898    519,1697    1005,1864    1155,1156    1725,1870    1748,1857

X(1776) = crosspoint of X(21) and X(1156)
X(1776) = crosssum of X(65) and X(1155)
