Because the contrapositive of a statement always has the same truth value (truth or falsity) as the statement itself, it can be a powerful tool for proving mathematical theorems (especially if the truth of the contrapositive is easier to establish than the truth of the statement itself). A proof by contraposition (contrapositive) is a direct proof of the contrapositive of a statement. However, indirect methods such as proof by contradiction can also be used with contraposition, as, for exa…

WebGiven statement: If a triangle ABC is an equilateral triangle, then all its interior angles are equal. To find the converse of a given statement, first we have to identify the statements P and Q. The given statement is in the form P ⇒ Q. Now, we have to find Q ⇒ P. Here, P = Triangle ABC is an equilateral triangle. WebSo then the deduction would be that C has to be less than zero, and we can't have negative angles. So right there, that is the contradiction. And then you would say, OK, therefore you cannot have two angles that are more than 90 degrees or two angles that are obtuse. And that would be your proof by contradiction.
