文[1]给出了两个几何结论及一个猜想,具体如下:定理1若凸m边形内有互不相同且任意三点都不共线的n(n∈N~*)个点,把这n个点再加上m边形的m个顶点共有m+n个点作为顶点,连线组成互不重叠的小三角形,则一共可以组成的小三角形的个数为f(m,n)=m+2n-2.定理2若四面体内有互不相同且任意四点不共面的n(n∈N~*)个点,把这n个点再加上四 Two geometric conclusions and a conjecture are given in [1], as follows: Theorem 1 If there are n (n∈N ~ *) points in convex m-polygon that are not the same with each other at any three points, The number of small triangles that can form a total of m triangles is m (m, n ) = m + 2n-2 Theorem 2 If there are n (n∈N ~ *) points in the tetrahedron different from each other and any four points are not coplanar, add these four points to four
