There are many fascinating results that do not appear in textbooks although they are accessible with a good knowledge of secondary-school mathematics. This book presents a selection of these topics including the mathematical formalization of origami, construction with straightedge and compass (and other instruments), the five- and six-color theorems, a taste of Ramsey theory and little-known theorems proved by induction. Among the most surprising theorems are the Mohr-Mascheroni theorem that a compass alone can perform all the classical constructions with straightedge and compass, and Steiner's theorem that a straightedge alone is sufficient provided that a single circle is given. The highlight of the book is a detailed presentation of Gauss's purely algebraic proof that a regular heptadecagon (a regular polygon with seventeen sides) can be constructed with straightedge and compass. Although the mathematics used in the book is elementary (Euclidean and analytic geometry, algebra, trigonometry), students in secondary schools and colleges, teachers, and other interested readers will relish the opportunity to confront the challenge of understanding these surprising theorems. 606 $aMathematics 606 $aComputer science 606 $aMathematics 606 $aComputer Science 606 $aMatemātica$2thub 608 $aLlibres electrōnics$2thub 615 0$aMathematics. 615 0$aComputer science. 615 14$aMathematics. 615 24$aComputer Science. 615 7$aMatemātica 676 $a510 700 $aBen-Ari$b Mordechai$4aut$4http://id.loc.gov/vocabulary/relators/aut$05385 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910592294503321 996 $aMathematical Surprises$92995566 997 $aUNINA
