The simulator below illustrates Napoleon's Theorem, which states that if equilateral triangles are erected externally (gray lines below) from each side of triangle Va-Vb-Vc (black lines below), then the centers of those triangles will always form an equilateral triangle (orange lines below). The orange triangle is the outer Napoleon Triangle.[br][br]The points A, B, and C can be moved to change the image.[br][br]In power system electrical engineering, the outer Napoleon Triangle represents the positive sequence component of the ABC phasor system. Phasors connecting the Va-Vb-Vc triangle center (white point below) to the corners of the orange triangle represent the positive sequence phasors rotated 180 degrees around the center.
