The Hinge Theorem (SAS Inequality Theorem): If two sides of one triangle are congruent to two sides of another triangle, and the included angles are not congruent, then the longer third side is opposite the larger included angle.
The Converse of Hinge Theorem (SSS Inequality Theorem): If two sides of one triangle are congruent to two sides of another triangle, and the third sides are not congruent, then the larger included angle is opposite the larger third side.
