## X(2181) (X(2)-ISOCONJUGATE OF X(97))

 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            a/f(a,b,c) : b/f(b,c,a) : c/f(c,a,b), where f(a,b,c) is as in X(97)
Barycentrics    a2/f(a,b,c) : b2/f(b,c,a): c2/f(c,a,b)

X(2181) lies on these lines:
19,31    33,2177    38,92    42,1859    158,774    244,278    281,756    896,1748    1118,1254    1193,1871    1857,2310    1953,2313

X(2181) = X(19)-Ceva conjugate of X(2179)
X(2181) = X(2179)-cross conjugate of X(1953)
X(2181) = crosspoint of X(19) and X(158)
X(2181) = corosssum of X(63) and X(255)
