If you assume that the conclusion is false, and you find a contradiction, then the only thing left to say is that the conclusion is true

So let's assume that the conclusion is false. If this assumption is made, and it leads to making one of the given statements to be false, then we run into a contradiction (since the given statements are taken to be true)
