is a continuous function and if [alpha], [beta] and [gamma] are the interior angles of a triangle, then the angles have been labeled so that the inequality f([alpha]) [greater than or equal to] f([beta]) [greater than or equal to] f([gamma]) holds.
For any triangle with interior angles [alpha], [beta] and [gamma], one has that f([alpha]) = f([beta]) = f([gamma]) = k which are the lengths of the sides of an equilateral triangle with sides of length k.
Suppose that [alpha], [beta] and [gamma] are the interior angles of a triangle.
Since f is not a TPF there exists a triangle with interior angles [alpha], [beta] and [gamma] such that f([alpha]), f([beta]) and f([gamma]) will not be the lengths of the sides of any triangle.
