平面几何是初中数学中两大组成部分之一,以图形为主体的初中几何,主要涉及三角形、四边形、圆等方面的知识.随着中考试题越来越注重学生利用数学知识处理实际问题的综合分析能力,近年来全国各个地区的中考数学试题中经常出现几何动点问题,成为中考数学试题的热点和难点之一.这类试题具有很强的灵活性,相对难度比较大,正是这种动态问题,让学生难以找出解决问题的切入口,给广大师生带来了不小的麻烦.本文笔者根据自身多年从事初中数学教学的经验,通过几道典型试题的解析
Plane geometry is one of the two major components of mathematics in junior high school, and its geometry is mainly composed of junior high school geometry, mainly involving the knowledge of triangle, quadrangle, circle, etc. With the examination questions more and more emphasis on students to use mathematical knowledge to deal with practical problems Analytical ability, in recent years in various parts of the country in the mathematics test questions often appear geometric moving point, become the entrance exam math problems hot and difficult one of these questions has a strong flexibility, relatively more difficult, it is this Dynamic problems, so that students find it difficult to find the entry point to solve the problem, to the majority of teachers and students brought a lot of trouble.This author according to my own experience in junior high school mathematics teaching for many years, through several typical test questions
