The Hinge theorem is called that because one of the sides of a triangle can swing like a hinge into two different positions that could solve a triangle problem. In geometry, the hinge theorem states that if two sides of one triangle are congruent to two sides of another triangle, and the included angle of the first is larger than the included angle of the second, then the third side of the first triangle is longer than the third side of the second triangle. The hinge theorem states that if two triangles have two congruent sides (sides of equal length), then the triangle with the larger angle between those sides will have a longer third side.
