截头棱柱的几个有趣性质４３４３００湖北省公安县第一中学徐宗才文［１］对１９９３年数学高考立几题作了系统研究，其实质涉及到截头棱柱的本质特性．所谓截头棱柱．即用不平行于棱柱底面的平面去截棱柱所得的几何体．本文通过探讨，得出截头棱柱的几个有趣性质．性质１... Several interesting properties of the truncated prism 434300 Xuzong Caiwen, the first middle school in the Public Security County of Hubei Province, made a systematic study on several problems in the 1993 mathematics college entrance examination. Its essence concerns the nature of truncated prisms. The so-called truncated prism. That is, the geometry obtained by truncating a prism is not parallel to the plane of the prism’s bottom surface. In this paper, some interesting properties of truncated prisms are obtained through discussion. Nature 1...
