全等三角形的习题,在解题思路和方法上,都具有几何题分析的典型性和代表性.在引导学生将知识转化为能力的过程中,充分发挥了典型习题的示范及启发作用,因此教师搭建课堂交流平台,创设激活思维的契机,重视全等三角形习题的挖掘,灵活运用全等三角形的性质和判定定理的能力就显得十分重要. Congruent triangle exercises have the typicalness and representativeness of the geometry problem analysis in the problem-solving ideas and methods. In the process of guiding students to transform knowledge into competence, they fully exert the demonstration and inspiration of typical problems. Teachers set up a classroom communication platform, create an opportunity for activating thinking, and pay attention to the excavation of trigonometric triangle exercises. It is very important to flexibly use the properties of congruent triangles and the ability to determine the theorem.
