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: (10.1 Mb).
This applet was built with the free and multiplatform dynamic geometry software C.a.R..

Trilinears           (a2 - bc)b2c2 : (b2 - ca)c2a2 : (c2 - ab)a2b2
Barycentrics    bc(a2 - bc) : ca(b2 - ca) : ab(c2 - ab)

X(350) lies on these lines:
1,76    2,37    11,325    33,264    36,99    42,308    55,183    69,497    86,310    172,384    190,672    256,314    291,726    305,614    320,513    447,811    519,668    538,1015    889,903

X(350) = isogonal conjugate of X(1911)
X(350) = isotomic conjugate of X(291)
X(350) = crosspoint of X(257) and X(335)
X(350) = crossdifference of any two points on line X(213)X(667)
X(350) = X(2)-Hirst inverse of X(75)
