Contradiction A contradiction is a disagreement between two statements, which means that both cannot be true. Proof by contradiction is a powerful technique. Proof by contradiction To prove a statement by contradiction you start by assuming it is not true. You then use logical steps to show that this assumption leads to something impossible (either a contradiction of the assumption, or a contradiction of a fact you know to be true). You can conclude that your assumption was incorrect an...
