 <content>The Lemoine point of a triangle, is the intersection point of its three symmedians. (That is, the isogonal conjugate of the centroid).

It is related with the Gergonne point by the following result: \\
On any triangle $ABC$, the Lemoine point of its Gergonne triangle is the Gergonne point of $ABC$.

In the picture, the blue lines are the medians, intersecting an the centroid  $G$.
The green lines are anglee bisectors intersecting at the incentre $I$ and the red lines are symmedians. The symmedians intersect at Lemoine point $L$.</content>
