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(1096)
Barycentrics (y + z) tan A : (z + x) tan B : (x + y) tan C, x : y : z = X(1096)
X(1899) lies on these lines:
2,98 3,68 4,51 5,1181 6,66 20,1204 25,1503 54,70 64,1885 69,305 154,468 235,1498 265,974 388,1425 394,1368 459,1495 511,1370 686,804X(1899) = reflection of X(394) in X(1368)
X(1899) = crosspoint of X(4) and X(69)
X(1899) = crosssum of X(I) and X(J) for these (I,J): (3,25), (52,418), (206,571)
