Napoleon points three triangles "XBC", "YCA", "ZAB" erected over the sides of the triangle "ABC" need not be isosceles for the three lines "AX", "BY", "CZ" to be concurrent. The concurrence of the lines "AX", "BY", and "CZ" holds even in much relaxed conditions. The following result states one of the most general conditions for the lines "AX", "BY", "CZ" to be concurrent. The point of concurrency is known as the Jacobi point. Coxeter and Greitzer state the Napoleon Theorem thus: "If equilateral triangles are erected externally on the sides of any triangle, their centers form an equilateral triangle". They observe that
