函数几何综合题是近几年来中考的热点，其目的是考查同学们综合运用函数知识和几何知识进行解题的能力．这类问题常见的有以下两种类型：一、几何元素间的函数关系问题这类问题的结构大多是已知几何图形，设置某些变量（如动点、动直线、动线段等），要求建立这些变量间的函数 The function geometry synthesis problem is a hot topic in the recent examinations. Its purpose is to examine the ability of students to use function knowledge and geometry knowledge to solve problems. Common problems of this type are the following two types: First, the function relationship between geometric elements The structure of such problems is mostly known geometry, set some variables (such as moving points, dynamic lines, line segments, etc.), requirements Create functions between these variables
