The Fermat point (also called the Torricelli point) of a triangle \triangle ABC is a point P which has the minimum total distance to three vertices (i.e., AP+BP+CP).

Construction

A method to find the point is to construct three equilateral triangles out of the three sides from \triangle ABC, then connect each new vertex to each opposite vertex, as these three lines will concur at first Fermat point.
