Consider a point P in the interior of an angle AOB, for each line
passing through P we obtain a triangle.
The triangle with minimal area is obtained when the line through P is
tangent to the exterior tangent circle of the two sides of the angle
passing in P.

Suplement question: what is the triangle with minimal area?
Let X be the point of tangency of the circunference I've just refered
with the near side of angle from the point P. I think the answer is
the triangle obtained with line PX, but i can't prove it.
