Visual Proof of the Pythagorean Theorem Using Grid Squares #117996 (License: Personal Use)

This diagram visually proves the Pythagorean theorem using three squares-red (left), green (bottom), and blue (hypotenuse-aligned)-with a yellow right triangle filling the gap between them. Each square is subdivided into unit grids to emphasize area equivalence: red (4×4) + green (3×3) = blue (5×5). The layout highlights how a² + b² = c² holds through spatial decomposition.

Used in math education websites, geometry lesson pages, or STEM resource hubs to explain the Pythagorean theorem intuitively; targets students, teachers, and self-learners seeking visual proofs.
