Abstract: | In this paper,we condider the relationship of three surface angles α1,α2,α3 starting from some vertex of a simplex in R3 with its Bottom Shape,we have proved whenA=1-cosα1001-cosα2-cosα301is positive subolefinite matrix,its bottom shape can be arbitrary triangle. |

Keywords: | Simplex Positive Subolefinite Matrix |
