WebTheorem: For any n ≥ 6, it is possible to subdivide a square into n squares. Proof: By induction. Let P(n) be “a square can be subdivided into n squares.” We will prove P(n) holds for all n ≥ 6. As our base cases, we prove P(6), P(7), and P(8), that a square can be subdivided into 6, 7, and 8 squares.
