几何定理的证明是学生获取知识、技能的重要学习内容,是锻炼学生思维的重要途径。《大纲》说:“数学教学要立足于学生的思维活动的展开,辅之以必要的讨论和总结,并加以正确的引导。”因此,定理的教学应向学生提供动眼、动脑、动手、动口的机会,想办法优化教学过程。经过多年的探索、实践, The proof of geometric theorem is an important learning content for students to acquire knowledge and skills, and it is an important way to train students’ thinking. The “Syllabus” said: “Mathematics teaching should be based on the development of students’ thinking activities, supplemented with necessary discussions and summaries, and guided properly.” Therefore, the teaching of the Theorem should provide students with an eye-opening, brain, and hands-on approach. Motivated by the opportunity to find ways to optimize the teaching process. After years of exploration and practice,
