∙ 10y agoTo 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.
Yes, because a variable cannot be both true and not true.

It's a contradiction . . . a statement that's not true.
2 must always equal 2. To have otherwise is a logical contradiction, and an impossibility.
you just used it in a sentence! He always contradicts what I say!
To prove by contradiction, you assume that an opposite assumption is true, then disprove the opposite statement.

Prove that if it were true then there must be a contradiction.
an identity? maybe a tautology? Comment by mgately: In the field of discrete mathematics (simplified the study of logic) any expression which always evaluates to true is in fact called a tautology. While less cool sounding, an expression which always evaluates to false is just called a contradiction.

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.

There doesn't seem to be a term "paradoximal." It might be a misspelling of "paradoxical," which means something that appears contradictory but may be true. Could you provide more context or clarify your question?
