图形的操作与图形的变换是新课程实施以来对传统平面几何改革变化最大的内容之一,也是近年来中考数学试题中的热点.图形的操作与图形的变换使原来静止的图形运动起来,不仅增加了试题的新颖性和开放性,而且能让学生经历操作、变换的全过程,提升学生的思维能力和创新意识.图形的操作与图形的变换是一种重要的数学思想方法,通过它可把几何图形运用“剪拼、分割、折叠、展开、平移变换、对称变换、旋转变换、相似变换、等积变换”等手段转化为解决问题需要的基本图形或特殊位置.
Graphic operation and graphics transformation is the new curriculum since the implementation of the traditional flat geometric changes one of the most changes in the content, but also in recent years the mathematical test questions in the hottest.Graphical operation and graphics transform the original static graphics movement, not only Increase the novelty and openness of the test questions, and allow students to experience the whole process of operation, change, improve students’ thinking ability and innovation awareness.Graphical operation and graphics transformation is an important mathematical method, through which The geometry is transformed into the basic graphic or special position needed to solve the problem by means of “cutting, splitting, folding, expanding, translating, symmetry, rotation, similarity, and transformation”
