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,称为最值问题.“线段和”最小值问题是初中数学的重要内容,是一类综合性较强的问题,也是中考的难点问题,它主要考察学生对平时所学的几何内容综合运用,海南中考的压轴函数与几何的综合题中也常出现.对这类题目大家感到无从下手,求解有一定的
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 The minimum value problem is called the most value problem. “The minimum value of the line segment and ” is the important content of junior high school mathematics, it is a kind of comprehensive strong question, also is the difficult question of the senior high school entrance exam, The comprehensive use of the geometric content, Hainan FLC function and geometry of the integrated questions often appear on the list of these people feel unable to start, there is a certain solution
