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(171)
Barycentrics (y + z) tan A : (z + x) tan B : (x + y) tan C, x : y : z = X(171)
X(1848) lies on these lines:
1,4 2,19 5,1871 7,1435 11,132 25,1001 27,86 28,1125 29,1842 92,264 286,350 427,1824 429,960 608,940 1595,1872 1828,1904 1883,1900X(1848) = isogonal conjugate of X(2359)
X(1848) = crosspoint of X(27) and X(92)
X(1848) = crosssum of X(I) and X(J) for these (I,J): (42,205), (48,71)
