G.GCO.7 Is "SSA" Legit? What Do You Think?
So far, we've learned a few theorems that help us prove two triangles congruent.  Recall these theorems are:
The SSS Theorem
The SAS Theorem
The ASA Theorem
Yet, what about "SSA"?  That is, if we have 2 sides and a "non-included" angle of one triangle congruent to 2 sides and a "non-included" angle of another triangle, can we conclude that the two triangles are congruent?
