## X(1428) (X(238)-BETH CONJUGATE OF X(238))

 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) = (1 - cos A)u(a,b,c), where u : v : w = X(238)
Barycentrics    af(a,b,c) : bf(b,c,a) : cf(c,a,b)

X(1428) lies on these lines:
1,182    3,613    6,41    31,1403    36,511    57,985    58,1178    59,518    60,757    65,82    184,614    238,1284    499,1352    611,999    651,1463    692,1279    961,1258    1456,1462

X(1428) = X(1416)-Ceva conjugate of X(56)
X(1428) = crosspoint of X(1014) and X(1462)
X(1428) = X(I)-Hirst inverse of X(J) for these (I,J): (31,1403), (56,604)
