X277
ISOGONAL CONJUGATE OF X218
X277 (ISOGONAL CONJUGATE OF X218) 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 \(f(A,B,C) = [\sec^{2}(A/2)]/[- \cos^{4} A/2 + \cos^{4} B/2 + \cos^{4} C/2]\)
Barycentrics: \(1/(a^{2} + b^{2} + c^{2} - 2 a b - 2 a c) : :\)
