It can be also extended from plane Euclidean geometry to higher dimension Euclidean spaces (e.g., to tetrahedra and more generally to simplices), as has been done for orthocentric tetrahedra (i.e., tetrahedra in which altitudes are concurrent)[2] and more generally for orthocentric simplices (i.e., simplices in which altitudes are concurrent).[3]. Without completing any calculations, use the hinge theorem to determine whether is greater than, less than, or equal to . While the jaw lengths of the alligator will not change, the jaw "hinge" does allow the alligator to open, or close, its mouth with varying angular degrees (at point A or D).

The converse of the hinge theorem is also true: If the two sides of one triangle are congruent to two sides of another triangle, and the third side of the first triangle is greater than the third side of the second triangle, then the included angle of the first triangle is larger than the included angle of the second triangle.

Theorem 6.12 Hinge Theorem 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 is longer than the third side of the second. Topical Outline | Geometry Outline | 0. Live Game Live. 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. If EF > BC, then m∠D > m∠B. 343 III. To prove the Hinge Theorem, we need to show that one line segment is larger than another.
