S-S-S Congruence Theorem

p. 236 #1-8, 16-19, 25, 27

25 and 27 are proofs.  I chose odd-number problems so that you can check your answers in the back of the book.  I suggest that you try the entire proof before you check your answers.  Then, if your results are way off, rework the proof, checking it line by line as you go.  If you have the right statements and reasons, but not in the same order as the text gives it, figure out what is important about their order, or what is not right with yours.  Just like the proof on the quiz where you could not use the contrapositive until after you had stated the conditional, sequence is important on these triangle congruence proofs, too.
