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!

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) = (a2 + b2 + c2 - 2bc)/(b - c)       (M. Iliev, 5/13/07)

X(1633) lies on these lines:
7,1486    19,1721    20,1610    28,1770    48,1742    59,1310    99,1310    100,190    101,1292    105,1086    108,109    497,1473

X(1633) = reflection of X(651) in X(692)
X(1633) = X(1275)-Ceva conjugate of X(6)
X(1633) = cevapoint of X(513) and X(1486)
X(1633) = crosspoint of X(I) and X(J) for these (I,J): (99,162), (100,934)
X(1633) = crosssum of X(512) and X(656)
X(1633) = X(I)-aleph conjugate of X(J) for these (I,J): (100,610), (1783,1707), (1897,19)
