{"product_id":"elementary-geometry-book-r-david-gustafson-9780471510024","title":"Elementary Geometry","description":"Although extensively revised, this new edition continues in the fine tradition of its predecessor. Major changes include: a notation that formalizes the distinction between equality and congruence and between line, ray and line segment; a completely rewritten chapter on mathematical logic with inclusion of truth tables and the logical basis for the discovery of non-Euclidean geometries; expanded coverage of analytic geometry with more theorems discussed and proved with coordinate geometry; two distinct chapters on parallel lines and parallelograms; a condensed chapter on numerical trigonometry; more problems; expansion of the section on surface areas and volume; and additional review exercises at the end of each chapter. Concise and logical, it will serve as an excellent review of high school geometry.","brand":"WoB","offers":[{"title":"US \/ WELL_READ \/ SBYB","offer_id":49917710991633,"sku":"CIN0471510025A","price":5.99,"currency_code":"USD","in_stock":false},{"title":"US \/ GOOD \/ SBYB","offer_id":49940473086225,"sku":"CIN0471510025G","price":5.99,"currency_code":"USD","in_stock":true},{"title":"US \/ VERY_GOOD \/ SBYB","offer_id":52698129269009,"sku":"CIN0471510025VG","price":5.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/0471510025.jpg?v=1786111451","url":"https:\/\/www.worldofbooks.com\/products\/elementary-geometry-book-r-david-gustafson-9780471510024","provider":"World of Books ","version":"1.0","type":"link"}
