This GeoGebra applet demonstrates a proof without words of the Pythagorean theorem using projection methods. By constructing semicircles, polygons, orthogonal lines, and intersections, it visually and dynamically illustrates the geometric essence of the relationship between the squares of the sides of a right triangle. The construction is intuitive and rigorous, making it suitable for teaching geo
