立体几何学科的特点决定了立体几何综合题的基本模式是论证、推理与计算相结合。高考立体几何解答题以多面体或旋转体为载体,主要考查平面的性质、空间两直线、直线和平面、两个平面的位置关系以及空间角、距离、面积、体积等,其中对点、线、面的位置关系的探究和证明是主旋律。解答立体几何证明题,一是要求知识结构明晰而完善(知识梳理到位,如证明线线垂直有哪些方法,平行关系的转化,垂直关系的转化,平行与垂直的联系等等),文字语言、符号语言、图形语言能灵活准确地进行转化;二是"由已知想性质,由求证想判定,分析与综合相结合来寻找证
The characteristics of the three-dimensional geometry discipline determine the basic mode of the three-dimensional geometric synthesis problem is the combination of argumentation, reasoning and calculation. College entrance examination three-dimensional geometry solution to the polyhedron or rotating body as the carrier, mainly to examine the nature of the plane, the space of two straight lines, lines and planes, the location of the two planes and the space angle, distance, area, volume, etc., of which the point, line, The exploration and proof of the positional relationship of the surface is the main theme. Answering the three-dimensional geometry proving question, the first is to require the knowledge structure to be clear and consummate (knowledge combing into place, such as the proof of vertical line method, the transformation of parallel relationship, the transformation of vertical relationship, the connection between parallel and vertical, etc.), text language, Symbolic language and graphic language can be converted flexibly and accurately; secondly, it is a combination of the known nature, the confirmation, the analysis, and the synthesis.
