2019-07-23 10:28
This GeoGebra applet demonstrates the classic Parallel Line Illusion. Using Polygon and Sequence commands, it constructs a specific geometric pattern showing how strictly parallel lines appear non-parallel, curved, or tilted due to visual interference from intersecting segments or repeated polygons. Users can adjust slider parameters m, n, and s to modify pattern density, angles, and spacing in re
