Euclid's Proof of the Pythagorean Theorem

This GeoGebra applet demonstrates the classic Euclidean geometric proof of the Pythagorean theorem. By constructing a right-angled triangle and the squares on its sides, it visually illustrates that the sum of the areas of the squares on the two legs equals the area of the square on the hypotenuse, using area dissection and congruent triangles. This dynamic construction helps deepen the understand
