     七巧板又称七巧图、智慧板,是汉族民间流传的智力玩具。它是由宋代的宴几演变而来的,原为文人的一种室内游戏,后在民间演变为拼图板玩具。据清代陆以湉《冷庐杂识》说::宋黄伯思宴几图,以方几七,长段相参,衍为二十五体,变为六十八名。明严瀓蝶几图,则又变通其制,以勾股之形,作三角相错形,如蝶翅。其式三,其制六,其数十有三,其变化之式,凡一百有余。近又有七巧图,其式五,其数七,其变化之式多至千余。体物肖 形,随手变幻,盖游戏之具,足以排闷破寂,故世俗皆喜为之。”现七巧板系由一块正方形切割为五个小勾股形,将其拼凑成各种事物图形,如人物、动植物、房亭楼阁、车轿船桥等,可一人玩,也可多人进行比赛。利用七巧板可以阐明若干重要几何关系,其原理便是古算术中的“出入相补原理”。
