## X(287) (X(2)-HIRST INVERSE OF X(98))

 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           cot A sec(A + ω) : cot B sec(B + ω) : cot C sec(C + ω)
Barycentrics    cos A sec(A + ω) : cos B sec(B + ω) : cos C sec(C + ω)

X(287) lies on these lines:
2,98    6,264    69,248    83,217    95,141    185,384    193,253    293,306    297,685    305,394    401,511    651,894    879,895

X(287) = reflection of X(648) in X(6)
X(287) = isogonal conjugate of X(232)
X(287) = isotomic conjugate of X(297)
X(287) = X(290)-Ceva conjugate of X(98)
X(287) = cevapoint of X(2) and X(401)
X(287) = X(248)-cross conjugate of X(98)
X(287) = X(2)-Hirst inverse of X(98)
