一、考点说明几何变换是中考的重难点,需要扎实的几何图形识别能力和理解能力,这类题关键是要掌握几何变换的本质,熟练应用各类变换的基本性质,抓住题干中的有效信息,找到解决问题的切入口,特别关注此类题中分类讨论的数学思想以及解题过程中的类比思想,多画图,简化图形都是解决这类问题的有效方法.二、命题趋势以图形的翻折,旋转为背景,考查学生解决数
First, the test center description Geometric transformation is a heavy test of the difficulty, the need for a solid geometry recognition and understanding ability, the key to such questions is to master the essence of geometric transformation, skilled application of the basic nature of various types of transformation, Effective information, to find the entry point to solve the problem, with particular attention to the mathematical thinking discussed in this category and analogy, multi-drawing, simplified graphics are all effective ways to solve such problems. Graphic fold, rotation as the background, examine the number of students to solve
