作为反映几何图形性质的最值问题,一直是横亘在学生心中的一道坎,它经常在中考试题中,以最值为载体,可以涵盖中学数学的所有知识点,考查分类讨论、数形结合、转化与化归等诸多数学思想和方法,具有较强的综合性.画图探究、几何变换和利用几何性质、几何问题代数化等方法是常用求解方法.本文拟着重探索如何合理运用定量条件,寻求最值问题的转化策略.一、添辅助圆巧助推垂直关系是中学数学重点研究的位置特
As a reflection of the nature of the geometric properties of the most valuable issue, has been lying in the hearts of students a hurdle, it is often in the examination questions, the most value as a carrier, you can cover all the knowledge of high school mathematics point to examine the classification discussion, Transformation and transformation, and many other mathematical ideas and methods, with a strong comprehensive.Picture exploration, geometric transformation and the use of geometric properties, geometric problems such as algebra is a common method of solving.This paper will focus on exploring the rational use of quantitative conditions, seeking Transformation strategy of the most value issues. First, add auxiliary round the vertical relationship is the focus of secondary mathematics research special position
