空间距离主要包括点点距离、点线距离、点面距离、线线距离、线面距离、面面距离。空间距离是立体几何研究的一类重要问题,其求法是历年高考重点考查的内容之一,其中以点到点的距离、点到线的距离、点到面的距离为基础,其他的空间距离都能转化为这三种距离来求解。一、定义法利用几何体、空间距离的定义,结合已知条件, The spatial distance mainly includes the point distance, the point line distance, the point surface distance, the line distance, the line surface distance, the surface distance. Spatial distance is one of the most important problems in the study of solid geometry. Its method of seeking is one of the key aspects of the college entrance examination in recent years. Based on the distance from point to point, the distance from point to line, the distance from point to plane, other spatial distances Can translate into these three distances to solve. First, the definition of law The use of geometry, the definition of spatial distance, combined with known conditions,
