WebA Famous and Beautiful Proof Theorem: √2 is irrational. Proof: By contradiction; assume √2is rational. Then there exists integers p and q such that q ≠ 0, p / q = √ , and p and q have no common divisors other than 1 and -1. Since p / q = √2 and q ≠ 0, we have p = √2q, so p2 = 2q2. Since q2 is an integer and p2 = 2q2, we have that p2 is even. By our earlier result, … WebJul 19, 2024 · A direct proof is the most common form of proof in geometry.
