WebExample of Indirect Proof Sum of 2n even numbers is even, where n > 0. Prove the statement using an indirect proof. The first step of an indirect proof is to assume that 'Sum of even integers is odd.' That is, 2 + 4 + 6 + 8 + . . . .+ 2n = an odd number ⇒ 2 1 + 2 + 3 + 4 +... + n = an odd number ⇒ 2 × = an odd number WebTo learn more about using contradiction to prove something is true, review the lesson Indirect Proof in Geometry: Definition & Examples, which covers the following objectives: Define...

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.
