文[1]给出了过椭圆焦点的内接三角形的4个结论,最终解决了“内接三角形面积的最大值”问题.本文再给出7个结论,最终解决了“内接三角形周长的最大值”问题.这些内容既可作为教师参考,又可选择作为教师指导学生进行研究性学习的课题和资料.限于篇幅,这里省略探究过程,仅提供结论和相应的证明.
In [1], we give four conclusions about the inscribed triangles of oval focal point, and finally solve the problem of “the maximum value of the area of the inscribed triangle.” This article gives seven conclusions and finally resolves the problem of “ The maximum value of the circumference of the triangle ”These contents can be used as a reference for teachers, but also can be used as a teacher to guide students to research topics and information.For limited space, here to omit the inquiry process, only to provide conclusions and the corresponding proof.
