plane geometry

基本解释

Because of the influence of plane geometry's negative transfer and teaching tool's limits in expression, it is one of the difficult courses that students think.
但由于受平面几何知识负迁移的影响以及教学工具表达功能的限制，立体几何也是学生反映比较困难的课程之一。
Through the method in which a plane in space can be determined by normal and normal plane, the complicated problems in space geometry can be imaged into the problems in plane geometry.
用法线和法线平面确定空间平面位置的方法，将复杂的空间几何问题简化为平面几何问题。
We sum up the unified definition of the center real quadratic curve by working at the two locus problems of plane analytic geometry of advanced―maths.
通过对高中《平面解析几何》的两个求轨迹问题，总结出中心实二次曲线的一个统一的定义；

Suppose I want to do little piece of code that's going to do planar geometry, points in the plane.
好，因此我需要一些,把这些东西收集到，一起的一些方式。
