X3734¶
X6com(1st BROCARD TRIANGLE)
Let A'B'C' be the 1st Brocard triangle. Let A″ be the trilinear pole, with respect to A'B'C', of line BC, and define B″ and C″ cyclically. The lines A'A″, B'B″, C'C″ concur in X3734.
X3734 (X6com(1st BROCARD TRIANGLE)) constructed on acute reference triangle \((a, b, c) = (5, 6, 7)\) with unit baseline AB = \(1\).¶
