opposite
False(apex real answer) True. (apex FAKE ANSWER)
proof by contradiction
To prove a statement false, you need ONE example of when it is not true.To prove it true, you need to show it is ALWAYS true.
Root signs didn't show up
opposite
To prove by contradiction, you assume that an opposite assumption is true, then disprove the opposite statement.
Yes, that's how it is done. Assuming the contrary should eventually lead you to some contradiction.
False(apex real answer) True. (apex FAKE ANSWER)
Prove that if it were true then there must be a contradiction.
Proof in which one assumes the opposite of what you have to prove is indirect proof. In indirect proof a person can draw a conclusion from assuming the opposite is true and then find a conclusion.
Contradiction or indirect proof.
proof by contradiction
A statement to prove. It may be a theorem or not.A starting point that is based on information that is given.A sequence of steps based on logical application of axioms or theorems (in geometry or mathematics).These must conclude with the statement that you set out to prove.An alternative (reductio ad absurdum) is to start with the assumption of the truth of the negation of the statement that you wish to prove. Again using logical methods, show that this must lead to a contradiction and therefore, the assumption must be false and thus the statement must be true.
Yes. It is a theorem. To prove it, use contradiction.
