外心是三角形的重要性质,向量是高中数学的重要知识点,这两个知识点经常胶着在一起互相碰撞,各自发挥自己的特点,就形成了特殊的一些解决问题的方法.本文通过一些教学中的实例,来谈谈当向量遇到外心时产生的思维火花.
External is the important nature of the triangle, the vector is an important knowledge point of high school mathematics, these two knowledge points are often collided with each other collision, each play their own characteristics, formed a special way to solve the problem.Through some teaching In the example, to talk about when the vector encountered outside the spark of thinking.
