平面与平面平行的判定是立体几何推理证明的基本内容,对于研究平面与平面位置关系起到非常重要的作用.在学习判定面面平行的方法时,需从不同的角度去理解、掌握.下面就判定面面平行的四个基本方法进行举例分析:
The determination of the plane and the plane parallelism is the basic content of the proof of the stereogeometric reasoning, and plays a very important role in the study of the positional relationship between the plane and the plane. When learning the method of determining the parallelism of the plane, it is necessary to understand and grasp from different angles. Take an example analysis of the four basic methods that determine the parallelism of the surface:
