X(2188)
(X(2)-ISOCONJUGATE OF X(196))


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            a/f(a,b,c) : b/f(b,c,a) : c/f(c,a,b), where f(a,b,c) is as in X(196)
Barycentrics    a2/f(a,b,c) : b2/f(b,c,a): c2/f(c,a,b)

X(2188) lies on these lines:
1,1767    3,1433    48,55    57,972    73,972    73,939    84,943    212,577    268,1260    271,1792    282,284    1903,2268

X(2188) = isogonal conjugate of X(342)
X(2188) = X(I)-cross conjugate of X(J) for these I,J: 41,48    184,212
X(2188) = crosspoint of X(I) and X(J) for these I,J: 268,1433    271,282
X(2188) = crosssum of X(I) and X(J) for these I,J: 1,1767    208,223
