The Latin phrase is "reductio ad absurdum", meaning reduction to absurdity. You assume the opposite and show that logically it leads to a contradiction and therefore cannot be true.
The term that best describes a proof in which you assume the opposite of what you want to prove is 'indirect proof'.
proof by contradiction
True. (apex)
It is true.
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
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.
