1.现状几何是中学数学的一个重要组成部分,而立体几何是高中数学几何的重心.由于空间向量法的引入,传统立体几何的演绎推理相对减弱,这种现象不仅出现在学生答题中(学生偏向于运用空间向量法解决),而且在日常的课堂教学中也存在这种现象.目前人教A版必修2教材中主要的定理有4个“公理”、等角定理、直线与平面平行的判定定理、平面与平面平行的判定定理、直线与平面平行的性质定理、平面与平面平行的性质定理、直线与平面垂直的判
1. The status quo geometry is an important part of high school mathematics, and the solid geometry is the center of gravity of high school mathematics geometry. Due to the introduction of space vector method, the deduction of traditional solid geometry is relatively weakened. Which tends to be solved by using space vector method), and this phenomenon also exists in daily classroom teaching.At present, the main theorems in teaching A-compulsory 2 teaching materials include 4 axioms, equilateral theorem, straight line and plane Parallel judgment theorem, plane and plane parallel judgment theorem, straight line and plane parallel property theorem, plane and plane parallel property theorem, straight line and plane vertical judgment
