To prove by contradiction, you assume that an opposite assumption is true, then disprove the opposite statement.
Contradiction or indirect proof.
Yes. It is a theorem. To prove it, use contradiction.
Proof by contradiction (APEX)
The term that best describes a proof in which you assume the opposite of what you want to prove is 'indirect proof'.
TrueIt is true that the body of an indirect proof you must show that the assumption leads to a contradiction. In math a proof is a deductive argument for a mathematical statement.
To prove a statement by contradiction one begins by assuming the statement is not true. Contradiction is the act of giving the opposing something that you feel is not right.
opposite
A contradiction of a statement is a statement that proves the previous statement wrong.
In general a contradiction cannot be proved.
Prove that if it were true then there must be a contradiction.
The statement was a contradiction in itself.
The feature of a paradox is that it is contradictory. The contradiction can be a statement or an opinion.
An implicit contradiction, as opposed to an explicit contradiction, is hidden within the logical structure of the statement. If you figure it out, you will discover that there is a contradiction. Explicit contradictions don't have to be figured out, they merely have to be pointed out.
Contradiction or indirect proof.
proof by contradiction
An impossible statement. Perhaps conundrum, or better: paradox, contradiction. It could also be called 'undefined'.
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.
