中考数学题目每年看上去千变万化,但万变不离其宗,题目在变,实质不变。如每一类题型都有相似的解题思想,这种思想的集中体现,便是解题思路和方法。只有抓住解题思路和方法,我们才能从容应对几何综合题。《全等三角形》是学生进入初中以来,首次系统性地进行几何证明的学习。其中《全等三角形的判定》的学习,是在学生学习了全等三角形的概念、性质的基础上进行的。在知识结构上,它是证明线段相等、角相等的重要方法,而且后 The subject of math exams looks ever-changing every year, but the subject of change remains unchanged. For example, each type of question has a similar idea of ​​solving problems. The concentrated expression of such thinking is the way to solve problems. Only grasp the problem-solving ideas and methods, we can calmly deal with geometric synthesis questions. The “congruent triangle” is the first systematic and systematic proof of learning that students have made since entering junior high school. Among them, the study of “determination of congruent triangles” is based on the concept and nature of students learning the congruent triangles. In the knowledge structure, it is an important way to prove that the line segments are equal and the angles are equal, and later
