FontenéFirstTheorem::usage="There is a base triangle and an inner point v. If in the pedal triangle with respect to v and in the medial triangle, their sides are extended, they intersect at three different points. The lines that connect the vertices of the pedal triangle with these points are concurrent at a point where the 9-point circumference and the pedal circumference have one point in common, the point F.
