正多边形的一个性质

摘要

给出了当n阶完全图Gn的n个结点恰为一正n边形的顶点，且Gn的边为具有长度的直线段时，Gn的n(n-1)／2条边的边长与该正n边形的半径之间的关系.%Supose that Gn is a n-order complete graph sharing n vertexes with a regularrnn-gon. Under this condition, this paper gives a relation between the lengthes of Gns rnn(n-1)／2 edges and the radius of the regular n-gon.
