Using a systematic paper-folding procedure it is possible to construct a regular polygon with any number of sides. This remarkable algorithm has led to interesting proofs of certain results in number theory, has been used to answer combinatorial questions involving partitions of space, and has enabled the authors to obtain the formula for the volume of a regular tetrahedron in around three steps, using nothing more complicated than basic arithmetic and the most elementary plane geometry. All of these ideas, and more, reveal the beauty of mathematics and the interconnectedness of its various branches. Detailed instructions, including clear illustrations, enable the reader to gain hands-on experience constructing these models and to discover for themselves the patterns and relationships they unearth. 606 $aMathematics 606 $aPaper work 606 $aGeometrical models 606 $aPolyhedra$xModels 606 $aMathematics$xStudy and teaching 606 $aGeometry$xStudy and teaching 606 $aCombinatorial geometry$xStudy and teaching 606 $aMathematical recreations 615 0$aMathematics. 615 0$aPaper work. 615 0$aGeometrical models. 615 0$aPolyhedra$xModels. 615 0$aMathematics$xStudy and teaching. 615 0$aGeometry$xStudy and teaching. 615 0$aCombinatorial geometry$xStudy and teaching. 615 0$aMathematical recreations. 676 $a510 700 $aHilton$b Peter$f1923-2010,$042007 702 $aPedersen$b Jean 702 $aDonmoyer$b Sylvie 801 0$bUkCbUP 801 1$bUkCbUP 906 $aBOOK 912 $a9910459262403321 996 $aA mathematical tapestry$92443606 997 $aUNINA LEADER 01236nam0-2200373 --450 001 9910804883903321 005 20240220165544.0 020 $aIT$b1943 2713 100 $a20240220d1943----kmuy0itay5050 ba 101 $aita 102 $aIT 105 $a 001yy 200 1 $aRiproduzione e sessualitą nelle piante e negli animali$fJ.
