This applet demonstrates James A. Garfield's classic algebraic proof of the Pythagorean theorem. By constructing a trapezoid with three right triangles, it derives the theorem using area formulas and algebraic expansion. Using translation and angle tools, this model helps learners understand the integration of algebra and geometry, exploring alternative proofs of the Pythagorean theorem.
