Contrapositive of or
WebIn mathematics, proof by contrapositive, or proof by contraposition, is a rule of inference used in proofs, where one infers a conditional statement from its contrapositive. [2] In other words, the conclusion "if A, then B " is inferred by constructing a proof of the claim "if not B, then not A " instead. WebContrapositive: If I don't get wet, then it does not rain. The converse of a proposition is not necessarily logically equivalent to it, that is they may or may not take the same truth value at the same time. On the other hand, the contrapositive of a proposition is always
