一、前言《中学数学》(下)2014年第8期刊载了王四宝老师的文章《一道联考试题的分析过程与讲评设计》(下称文1),王老师对2013年浙江省绍兴市中考试题中的一道填空题进行了深度解读,并以此题为数学活动素材,设计了两个有趣的探究活动,不仅对本题的解答过程分析的一清二楚,而且对本题也做了拓展性的研究.从文1可以看出,王老师通过添加四条辅助线,利用轴对称的性质、平行四边形的判定与性质、矩形的性质、勾股定理、证明
I. Preface “Secondary Mathematics” (Part 2) The 8th issue of 2014 contains an article by Wang Sibao, “The Analysis Process and Design of a Joint Test Exam” (hereinafter referred to as “Text 1”). Teacher Wang to the 2013 Shaoxing Middle School in Zhejiang Province An in-depth explanation of the blank-filling question in the test was made, and this question was taken as the material of mathematics activities. Two interesting inquiries were designed. Not only did the analysis of the solution to the question clearly understood, but the topic was also extended. Study. It can be seen from Article 1 that through the addition of four auxiliary lines, Professor Wang uses the properties of axisymmetric, the determination and nature of parallelograms, the nature of rectangles, the Pythagorean theorem, and proofs.
