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 any side of any triangle, given the lengths of the other two sides and the angle between them. If the angle between the other sides is a right angle, the law of cosines reduces to the Pythagorean equation.
