摘要
建立适当坐标系,将几何的基本对象(点)和代数的基本对象(数)联系起来,运用向量的知识,将初等几何中的共点线问题转化为有关点的坐标的代数问题来研究。
Based on the establishment of the suitable coordinate system , the paper connects the basic object of geometry （point） with the basic object of algebra （number） , and through the application of vector, the paper transforms altogether the questions of lines through one point in elementary geometry into studies of algebra questions of the related spot coordinates.
