| Abstract: | This report tries to explore questions concerning dynamic solid geometry and its relations with threshold value and range in order to find out the tactics of solving the geometric problems.A particular threshold value is predetermined by the dynamic graph.And the study of threshold value of solid geometry often makes use of transformational method to mark its way of changes. |

| Keywords: | solid geometry threshold value range spatial angel |
