“赵爽弦图”是一种验证勾股定理的图形,利用它验证勾股定理的主要思想是:利用两种不同的方法计算同一图形的面积,得到的结果应该相等.命题人通常以直角三角形为载体,以数学结合、公式变形等重要的数学思想为依托,实现了对基础知识、基本技能、基本活动经验、基本数学思想的全面考查.同时,此种题型侧重考查学生异中求同,由形悟质的能力. The main idea of ​​using Pythagorean theorem to verify the Pythagorean theorem is to calculate the area of ​​the same graph by two different methods, and the results obtained should be equal. Propositional people usually use right angle Triangle as the carrier, mathematical mathematics, formula deformation and other important mathematical ideas as the basis, to achieve the basic knowledge, basic skills, basic activities experience, basic mathematical thinking of a comprehensive examination of the same time, The same, by the ability of enlightenment.
