2015年浙江省湖州市中考压轴题命制的最大特色是,试题由简单知识点的考查转变为对考生数学能力的考核,题型新颖.命题来源于最基本的旋转变换构成的全等三角形,并由此提出了层层递进的三个问题.主要涉及特殊三角形、一元二次方程根的判别式、二次函数图象与性质、三角形相似等多个知识点,渗透了数形结合,分类讨论思想等多种重要数学思想方法,具有一定的思维深度.本文通过湖州卷压轴题(第
In 2015, Huzhou City, Zhejiang Province, the finale of the most important feature is that the test questions from a simple knowledge point test into a test of mathematical ability of candidates, the new question.The proposition comes from the most basic transformation of the rotation of the congruent triangle, And then put forward three layers of progressive problems.Mainly related to the special triangle, the discriminant of the quadratic equation root quadratic function and the nature of the triangle similar to multiple knowledge points, penetrating the combination of number, Classification and discussion of ideas and other important mathematical ideas and methods, with a certain depth of thinking.This paper by Huzhou rolling axis (the first
