立体几何内容较为抽象,它要求考生具有一定的空间想象能力,会利用平面的基本性质及线线、线面和面面平行与垂直的判定与性质定理对命题真假进行判断。解答题主要考查线线、线面与面面平行和垂直关系,且多以棱柱、棱锥、棱台或其简单组合体为载体进行考查,要求考生识图有型、计算准确、推理规范。本文总结了考生在解答立体几何问题时常犯的几点错误。 Stereo geometry content is more abstract, which requires the examinee to have certain spatial imagination ability. Judgment will be made on the true nature of the proposition using the basic properties of the plane and the parallel and vertical determinations of the line, face and face. Answer questions mainly examine the line, line surface and surface parallel and vertical relationship, and more prism, pyramid, pyramid, or its simple combination of carrier as a carrier to examine, require the examinee cognitive figure, calculation accuracy, reasoning specifications. This article summarizes some of the mistakes that candidates make when solving solid geometry problems.
