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

X(2185) = isogonal conjugate of X(2171)
X(2185) = X(I)-Ceva conjugate of X(J) for these I,J: 249,662 261,1098 1509,757
X(2185) = cevapoint of X(I) and X(J) for these I,J: 1,572 21,284 81,1790
X(2185) = X(I)-cross conjugate of X(J) for these I,J: 21,261 60,757 284,60 2150,270
X(2185) = crosspoint of X(261) and X(1509)
X(2185) = crosssum of X(181) and X(1500)
