proof by contradiction
It is a type of indirect proof: more specifically, a proof by contradiction.
False
With an indirect proof, you temporarily assume that the opposite of what you're trying to prove is true. For example, let's say I'm trying to prove that the sky is blue. With an indirect proof, I would first say: "Assume temporarily that sky is not blue..." and go from there. Eventually, I will reach a contradiction and with this contradiction I can assume that this route of thinking is false, therefore my proof must be true.
Proof by contradiction is also known by its Latin equivalent, reductio ad absurdum.
