Lemoine point
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 , the Lemoine point of its Gergonne triangle is the Gergonne point of .
In the picture, the blue lines are the medians, intersecting an the centroid .
The green lines are anglee bisectors intersecting at the incentre and the red lines are symmedians. The symmedians intersect at Lemoine point .
