近几年的高考试题中,立体几何部分多次出现动态思维题型,其共同特征是“动”与“静”的辨证统一,怎样解答立体几何中的这种题型,使我们走出“静”的困惑,步入“动”的空间,这里关键是动静相互转化.一、动中蕴涵静,善于挖掘例1 如图1,在直棱柱ABC—A’B’C’中, In recent years, in the high-examination questions, the three-dimensional geometric part has appeared many times in the dynamic thinking question type. Its common feature is the dialectical unity of “move” and “quietness”. How to answer this question type in the three-dimensional geometry makes us get out of “static The perplexity of the “walking” space is the key to the mutual transformation of the movements. First, the implication in the movement, and the excavation of examples 1 As shown in Figure 1, in the straight prism ABC-A’B’C’,
