contradiction
It is a type of indirect proof: more specifically, a proof by contradiction.
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.
The term that best describes a proof in which you assume the opposite of what you want to prove is 'indirect proof'.

An indirect proof is a proof by contradiction.
contradiction
An indirect proof is another name for a proof by contradiction. This is where the original premise is assumed to be false and then attempted to be proven. Because this proof turns out to be false, the original premise is then true.
Proof in which one assumes the opposite of what you have to prove is indirect proof. In indirect proof a person can draw a conclusion from assuming the opposite is true and then find a conclusion.

Proof by contradiction is also known by its Latin equivalent, reductio ad absurdum.
