X(1398)
(X(34)-BETH CONJUGATE OF X(34))


Click here to access the list of all triangle centers.

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 Run Macro Tool, select the center name from the list and, then, click on the vertices A, B and C successively.

The JRE (Java Runtime Environment) is not enabled in your browser!

Download all construction files and macros: tc.zip (10.1 Mb).
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(34)
Barycentrics    af(a,b,c) : bf(b,c,a) : cf(c,a,b)

X(1398) lies on these lines:
1,1037    4,496    6,1425    25,34    28,279    184,221    278,961    388,427    475,956    604,608    607,1475    1106,1395    1254,1460    1394,1473    1407,1408

X(1398) = isogonal conjugate of X(1265)
X(1398) = X(I)-Ceva conjugate of X(J) for these (I,J): (1119,1407), (1435,608)
X(1398) = X(1395)-cross conjugate of X(608)
