One can wonder if the ASA, SSA, etc. theorems can be generalized to quadrilaterals. For example, does ASAS uniquely determine a quadrilateral? Does SSSS? Actually, one can show (I think) that for quadrilaterals, 4 pieces of information (any combination of 4 A's or S's) will never uniquely determine a quadrilateral. However, if you have 5 pieces of information, it seems like it should have a good chance of determining a quadrilateral. 11. Show that SASAS uniquely determines a quadrilateral: Solve the quadrilateral for SASAS=5,40 ,6,35 ,7 12. For what combination of S's and A's is the quadrilateral semi-uniquely determined, meaning there are two choices for the quadrilateral
