ORTHOCORRESPONDENT OF X80
X2006 (ORTHOCORRESPONDENT OF X80) constructed on acute reference triangle \((a, b, c) = (5, 6, 7)\) with unit baseline AB = \(1\).
Trilinears: \(f(a,b,c) : f(b,c,a) : f(c,a,b)\), where
\(f(a,b,c) = yz + (-x \cos A + y \cos B + z \cos C)x\), where
\(x : y : z\) =
X80
Barycentrics: \(af(a,b,c) : bf(b,c,a) : cf(c,a,b)\)

Trilinears: \(\sin(A/2) \sec(3A/2) : \sin(B/2) \sec(3B/2) : \sin(C/2) \sec(3C/2)\) (M. Iliev, 4/12/07)
Trilinears: \((\tan A/2)/(1 - 2 \cos A) : (\tan B/2)/(1 - 2 \cos B): (\tan C/2)/(1 - 2 \cos C)\) (M. Iliev, 4/12/07)
Trilinears: \(g(a,b,c) : g(b,c,a) : g(c,a,b)\), where \(g(a,b,c) = bc/[(b + c - a)(b^{2} + c^{2} - a^{2} - bc)]\) (M. Iliev, 5/13/07)
