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 ...
Theon of Alexandria (/ ˌ θ iː ə n,-ɒ n /; Ancient Greek: Θέων ὁ Ἀλεξανδρεύς; c. AD 335 – c. 405) was a Greek [1] scholar and mathematician who lived in Alexandria, Egypt.
The hinge theorem is there, and more theorems are on the way. I think that this is a very credible source. 72.86.118.208 19:55, 27 May 2010 (UTC) I can vouch for the ...

A twist-hinge dissection is one which use a three-dimensional "hinge" which is placed on the edges of pieces rather than their vertices, allowing them to be "flipped" three-dimensionally. [ 10 ] [ 11 ] As of 2002, the question of whether any two polygons must have a common twist-hinged dissection remains unsolved.
The app allows you to display three Hinge prompt answers, with a myriad of options to choose from (including voice and video prompts!). These range from funny, to deep, to nerdy.
Ctesibius' water clock, as visualized by the 17th-century French architect Claude Perrault. Ctesibius or Ktesibios or Tesibius (Ancient Greek: Κτησίβιος; fl. 285–222 BCE) was a Greek inventor and mathematician in Alexandria, Ptolemaic Egypt. [1]
Hinge’s parent company, which also owns Tinder, OkCupid, Match.com, The League, and more, disappointed investors last fall. Its third-quarter earnings showed a 6% year-over-year decline in ...
