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 1/f(a,b,c) : 1/f(b,c,a) : 1/f(c,a,b), where f(a,b,c) is as in X(1172)
= cot A (cos B + cos C) : cot B (cos C + cos A) : cot C (cos A + cos B) (Darij Grinberg, 4/11/03)
X(1214) lies on these lines:

X(1214) = isogonal conjugate of X(1172)
X(1214) = complement of X(92)
X(1214) = X(I)-Ceva conjugate of X(J) for these (I,J) : (2,226), (77,73), (307,72), (348,307)
X(1214) = cevapoint of X(I) and X(J) for these (I,J): (37,227), (71,73)
X(1214) = X(I)-cross conjugate of X(J) for these (I,J): (71,72), (201,307)
X(1214) = crosspoint of X(I) and X(J) for these (I,J): (2,63), (77,348), (1231,1441)
X(1214) = crosssum of X(I) and X(J) for these (I,J): (6,19), (33,607)
