20 What is SAS and SSS.

21 Instead of showing that the conclusions are true you show all the alternatives are false. Assume the negation of the original statement, use deductive reasoning and get two contradicting statements that cannot both be true.

22 What is indirect proof

23 For all integers n, 4(n 2 + n + 1) − 3n 2 is a perfect square. Proof: Let n is any [particular but arbitrarily chosen] integer. [We must show that (4(n 2 + n + 1) − 3n 2 ) is a perfect square.] Then, we have 4(n 2 + n + 1) − 3n 2 = 4n 2 + 4n + 4 − 3n 2 = n 2 + 4n + 4 = (n + 2) 2 But is a perfect square [because (n+2) is an integer (being a sum of n and 2).] Hence, (4(n 2 + n + 1) − 3n 2 ) is an integer, as was to be shown. And this completes the proof. True or False

24 What is True.
