This GeoGebra applet is designed to demonstrate the calculation principle and derivation of the area of a parallelogram. By constructing segments, rays, orthogonal lines, and intersections, combined with geometric transformations and congruent properties, it visually shows how to transform a parallelogram into a rectangle of equal area by drawing altitudes and using the cut-and-paste method.
