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

Trilinears (y + z) sec A : (z + x) sec B : (x + y) sec C, x : y : z = X(1249)
Barycentrics (y + z) tan A : (z + x) tan B : (x + y) tan C, x : y : z = X(1249)
X(1903) lies on these lines:
3,9 6,33 19,64 37,73 65,1826 69,189 71,210 226,1439 285,1798 478,1413 1419,1422X(1903) = isogonal conjugate of X(1817)
X(1903) = crosspoint of X(84) and X(189)
X(1903) = crosssum of X(I) and X(J) for these (I,J): (3,610), (40,198)
