LeMoine Point<br />
The symmedians of a triangle are concurrent at the<br />
LeMoine point (also called the symmedian point).<br />
This is a consequence of a more general result, namely:<br />
Theorem: The isogonal conjugates of a set of<br />
concurrent segments from the vertices to the opposite<br />
sides of a triangle are also concurrent.<br />
To prove this theorem we should recall the Law of<br />
Sines for a triangle.
