What reason do they give for disagreeing with you?' What reason do you have for your answer? Why are you not sure?

For your side what theorems are you applying in each case? For their side, so they have a counterexample to II?

Truth is not about the number of votes, but the validity of the thinking. (The reasoning here is a little subtle, so I understand how you might get it wrong ...)

Think how SAS congruence is proven between two triangles.
