圆看做是离心率e=0的特殊的圆锥曲线,因此,笔者在多年的教学实践中,通过类比总结,发现圆的垂径定理在有心圆锥曲线中也有类似结论.本文以定理形式给出它的一个推广,并举例说明其应用.
As a special conic curve with eccentricity e = 0, the author finds out that the theorem of circular diameter theorem also has a similar conclusion in the conic curve of concentricity through many years of teaching practice.According to the theorem It’s a promotion, and an example of its application.
