To prove by contradiction, you assume that an opposite assumption is true, then disprove the opposite statement.
Yes, if two of the angles in a triangle are obtuse or right, theres no logical way for the legs to meet at a point.
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.

True
No, this would be a logical contradiction.
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.
In Formal Logic proofs, the contradiction is represented with an inverted T (or upside-down T) as follows: ┴ The contradiction symbol can be introduced at any time a logical contradiction is encounterd, for example, all of the the following contradictory logical statements (using different symbols) can be replaced with the contradiction symbol: The ball is completely blue and the ball not completely blue. P ^ ¬P P & ~P P & !P P AND NOT P
Contradiction is logical incompatibility between two or more things. When two propositions have two conclusions that are opposite inversions of each other a contradiction is formed.
2 must always equal 2. To have otherwise is a logical contradiction, and an impossibility.
A contradiction is a fact or statement that questions or disproves an existing one. It is a logical conflict or incongruity, or one that cannot be reconciled with another. (A "contradiction in terms" is something that seems to contain self-contradictory elements, as in an oxymoron.) Example : "The crime scene analysis was a direct contradiction of the suspect's version of the events."
A contradiction occurs when two statements or ideas conflict with each other, leading to a logical inconsistency. This means that both statements cannot be true at the same time. In formal logic, a contradiction can invalidate an argument or theory.
Such is a contradiction: you cannot have a prime number that is not prime. This is a logical impossibility.
The Top looks nice, But i Don't like it To call the Pope an atheist, is a contradiction.
This is the composition of proof by contradiction upon logical negation.
No. It is a logical contradiction for something to be both real and not real: it must be one or the other. In the case of mermaids, they are not real.
