The hinge theorem holds in Euclidean spaces and more generally in simply connected non-positively curved space forms.. 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 ...
John Newton proved the hinge theorem. Does that make it reliable? Squall BL The FMA just released an expansion of the Hinge Theorem on spp15.emagc.com. Click on the "Daily Rabble" tab to see the more reliable info. This information is groundbreaking, and it may merit an article for the hinge theorem. Squall BL 22:16, 28 May 2010 (UTC)

An ornate brass door hinge A barrel hinge. A hinge is a mechanical bearing that connects two solid objects, typically allowing only a limited angle of rotation between them. Two objects connected by an ideal hinge rotate relative to each other about a fixed axis of rotation, with all other translations or rotations prevented; thus a hinge has one degree of freedom.
