X(2635)
(SUM OF PU(76))


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) = sec B + sec C - 2 sec A
Barycentrics    (sin A)f(A,B,C) : (sin B)f(B,C,A) : (sin C)f(C,A,B)

X(2635) lies on these lines:
1,4    11,1458    42,1836    44,513    209,2390    329,2318    411,1935    651,1936    774,1898    823,2659    908,1818    971,1465    1042,1837    1044,1788    1156,1937    1254,1858    1427,1864    1758,1776

X(2635) = crosssum of X(I) and X(J) for these I,J; 1,2635    2637,2638
