## X(148) (STEINER POINT OF ANTICOMPLEMENTARY TRIANGLE)

 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) = bc[a4 - (b2 - c2)2 + b2c2 - a2b2 - a2c2]

Barycentrics    g(a,b,c) : g(b,c,a) : g(c,a,b), where g(a,b,c) = a4 - (b2 - c2)2 + b2c2 - a2b2 - a2c2

X(148) = X(99)-of-anticomplementary triangle

X(148) lies on these lines: 2,99    4,147    13,617    20,98    30,385    146,193    316,538

X(148) = reflection of X(I) in X(J) for these (I,J): (2,671), (20,98), (99,115), (147,4), (616,14), (617,13)
X(148) = anticomplementary conjugate of X(512)
X(148) = X(523)-Ceva conjugate of X(2)
X(148) = X(2)-Hirst inverse of X(115)
