在历年的中考题中,以加菲尔德证明勾股定理时所采用的构图为基础进行演变,形成一类基本图形,结合平行四边形、平面直角坐标系、函数知识的综合题目,它们都可由两个三角形相似得到相应的边之间的关系,从而进行解题。引导学生注重对已获得的知识、解题经验进行归纳和转化,进一步发展解题能力,提高中考复习的有效性。
In the past years of the senior high school entrance examination questions, Garfield developed the Pythagorean theorem based on the composition used to form a basic graph, combined with parallelogram, Cartesian coordinate system, the comprehensive knowledge of function, they can be two Triangles are similar to get the relationship between the edges, in order to solve the problem. Guide students to pay attention to the knowledge gained, problem solving experience induction and transformation to further develop the ability to solve problems and improve the validity of the exam review.
