X2468 (EXSIMILICENTER(ORTHOCENTROIDALCIRCLE, SPIEKER CIRCLE)) constructed on acute reference triangle \((a, b, c) = (5, 6, 7)\) with unit baseline AB = \(1\).

Constructed Elements

Trilinears: \(f(a,b,c) : f(b,c,a) : f(c,a,b)\), where \(f(a,b,c) = bc[a \cos A + 4a \cos B \cos C - (b + c)J]\), J as at X1113
Barycentrics: \(af(a,b,c) : bf(b,c,a) : cf(c,a,b)\)
