在平面几何的动态问题中,当某几何元素在给定条件变动时,求某几何量(如线段的长度、图形的周长或面积、角的度数以及它们的和与差)的最大值或最小值问题,称为几何最值问题.近年来,各地中考题常通过几何最值问题考查学生的实践操作能力、空间想象能力、分析问题和解决问题的能力.本文针对不同类型的几何最值问题作一总结与分析,希望对大家有所帮助.最值问题的解决方法通常有如下两大类:一、应用几何性质
In the dynamic problem of plane geometry, when a geometric element changes in a given condition, find the maximum value of a geometric quantity (such as the length of the line segment, the circumference or area of the graphic, the degree of the angle and their sum and difference) or In recent years, the test questions around the world often through the geometric maximum value problem to examine students’ practical ability, spatial imagination ability, problem analysis and problem solving.This paper aims at different types of geometric maximum value The problem to make a summary and analysis, I hope to be helpful to you. The solution to the most value problems usually have the following two categories: First, the application of geometric properties
