Convex Polygons of Tangrams and the Geometric Invariants System

摘要: 本文给出了七巧板凸多边形的完全几何不变量系统，并以此建立了相应的方程组以及约束条件，从而给出了七巧板凸多边形计数问题的一个一般解决方案。

Abstract: In this paper, we give out the complete geometric invariants of the convex tangrams polygons, by which we establish equations with constraint conditions. Then, we obtain a general approach to find the number of the convex tangram polygons.
