一题多解是培养同学们创新思维能力的一条有效途径.而要实现一题多解,必须能多角度分析思考,探求多种解题方法.在立体几何教学中,笔者认为向量法、坐标法、几何法是解决立体几何问题的三种方法,亦可称为立体几何学习中的“三剑客”.向量法是指根据空间向量的基本定理,运用向量 The multi-explanation of the question is an effective way to cultivate the students’ creative thinking ability. To achieve a multi-solution to a question, we must be able to analyze and think from multiple angles and explore a variety of problem-solving methods. In stereo geometry teaching, the author believes that the vector method, coordinates The methods of law and geometry are three methods to solve the problem of three-dimensional geometry. They can also be called “three swordsmen” in the study of solid geometry. The vector method is based on the basic theorem of the space vector and uses vectors.
