推理作图法在求相贯线特殊点中的运用探讨

The aplication and inquiryof the way of inference drawiing in solving special point of intersection line

本文主要针对两基本几何体相交求画相贯线中特殊点的求解方法,阐述推理作图法的运用,其核心是三面共点法的推理运用。本文中列举了利用圆球面及圆锥面作辅助面求特殊点的推理作图法,可供学生学习参考。

This paper is directed the Solution of special point of two basic geome trie form intersect and drawing intersection. Expounding application of inference drawing and the Remet is inference application of the way in three swrfaces who used same point. The article lists untilizing spherical surface and spherical cone snrface to drauing auxiuiary surface to solve inference drawing of special point and offer reference for students.
