高中阶段的几何题,往往采用的是建立直角坐标系,将几何问题转化为代数问题来解决,但是由于直角坐标系的特殊性,并非所有的题目都容易建立直角坐标系,仿射坐标系在建系上比较灵活,而且学生容易掌握.
High school geometry problems, often used to establish a rectangular coordinate system, to solve the geometry problem into algebra problems, but due to the particularity of the rectangular coordinate system, not all topics are easy to establish a rectangular coordinate system, affine coordinate system in The building system is more flexible, and students are easy to master.
