{"product_id":"piano-hinged-dissections-time-to-fold","title":"Piano-Hinged Dissections: Time to Fold!","description":"A dissection involves cutting a polygon into pieces that form another polygon; for a hinged dissection, the pieces must be attached by hinges. A piano hinge is a long, narrow hinge with a pin running the entire length of its joint. Unlike regular hinged dissections, which swing around a single hinge point, piano-hinged dissections fold along an edge. This book discusses the history, methods, and variations of these dissections and is rich with illustrations that depict the cuts of the dissections and three-dimensional simulations of the dissection process. The downloadable resources include video recordings of select dissections being folded.","brand":"Thryft Singapore","offers":[{"title":"Like New","offer_id":52256014369049,"sku":"QA95.F693 2006","price":52.0,"currency_code":"MYR","in_stock":false},{"title":"Very Good","offer_id":52256014401817,"sku":"QA95.F693 2006","price":44.0,"currency_code":"MYR","in_stock":true},{"title":"Good","offer_id":52256014434585,"sku":"QA95.F693 2006","price":41.0,"currency_code":"MYR","in_stock":false},{"title":"Well Read","offer_id":52256014467353,"sku":"QA95.F693 2006","price":37.0,"currency_code":"MYR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0110\/0598\/4849\/files\/2028142.jpg?v=1776871617","url":"https:\/\/thryft.my\/products\/piano-hinged-dissections-time-to-fold","provider":"Thryft","version":"1.0","type":"link"}
