Pythagoras Theorem Dynamic Geometry Demonstration

① This GeoGebra example interactively demonstrates the Pythagorean theorem by constructing squares on the three sides of a right triangle, showing that the sum of the areas of the two smaller squares equals the area of the largest square. ② Core mathematical concepts include right triangles, the Pythagorean theorem, area relationships, geometric construction, and dynamic verification. ③ Construction highlights: from the summary, it uses commands such as Semicircle, Point, Circle, Polygon, OrthogonalLine, Intersect, Line, Segment, InteriorAngles, Midpoint, PointIn, and Distance to build the right triangle and squares on its sides, with auxiliary lines, angle labels, and area computations to illustrate the theorem. ④ Suitable for middle school geometry lessons, theorem exploration, or student self-study, and useful for teachers creating dynamic courseware to help learners grasp the geometric meaning of the Pythagorean theorem.
