more ... The Triangle Inequality Theorem says: Any side of a triangle must be shorter than the other two sides added together. If it was longer, the other two sides coudn't meet! Try moving the points below. ../geometry/triangle-inequality-theorem.html.
A generalization of this theorem is the law of cosines, which allows the computation of the length of the third side of any triangle, given the lengths of two sides and the size of the angle between them. If the angle between the sides is a right angle it reduces to the Pythagorean theorem.
