一、教育价值全等三角形是平面几何的重要内容,它为初中几何解决线段和角的相等问题提供了重要工具,也为其他几何知识的学习奠定了必要基础.可以说,学好全等三角形是几何入门的关键.二、考试要求全等三角形在中考中所占的分值较重,约7分,另外在解决其他几何问题时也经常要用到全等三角形判定与性质,因此它是中考中考查的重点.其考查的内容标准是:(1)理解全等三角形的概念,能识别全等三角形中的对应边、对应角.(2)掌握基本事实:两边及其夹角分别相等的两个
First, the equal value of education Triangle is an important part of plane geometry, which provides an important tool for junior high school geometry to solve the problem of equal line and angle, but also laid the necessary foundation for the learning of other geometric knowledge can be said that learning congruent triangles is The key to geometry entry two, examination requirements congruent triangle in the senior high school entrance examination in the score value heavier, about 7 points, in addition to solve other geometric problems often also use congruent triangle judgment and nature, so it is the test (1) to understand the concept of congruent triangles, recognizing congruent triangles in the corresponding side, the corresponding angle (2) to grasp the basic facts: the two sides and their angles are equal Two
