关于二面角的图形的绘制方法,在高中立体几何课本及有关参考书中,均未提及,因此教师对此问题不够重视,形成在课堂上缺乏系统的讲解,而仅是对某些具体问题上讲解一些画法,这样就造成学生在做作业时对于二面角图形的画法,感到很大的困难,甚至影响了作业的完成;同时教师在批改作业时,对于图形的修改亦成为一种繁琐的负担,为了克服这种困难,作者愿对二面角图形的绘制方法,提出一些初步意见,以供参考,并请指正。
The drawing method of the dihedral angle is not mentioned in the high school solid geometry textbooks and related reference books. Therefore, teachers do not pay much attention to this problem and form a lack of systematic explanation in the classroom, but only for certain specific Some of the painting techniques were explained on the issue. This caused students to feel great difficulty in drawing the dihedral drawing when doing their homework. It even affected the completion of the assignment. At the same time, when the teacher revised the assignment, the modification of the drawing became A kind of cumbersome burden, in order to overcome this difficulty, the author is willing to dihedral drawing method, put forward some preliminary opinions for reference, and please correct me.
