The Missing Area (II): Polygon Rearrangement and Area Illusion

2014-11-10 14:31
This applet demonstrates the classic 'missing area' geometric paradox. By cutting and rearranging polygons, the total area appears to change. This illusion occurs because the rearranged diagonal is not a strict straight line, containing a tiny gap or overlap. Constructing multiple polygons visually presents this, helping learners understand slope, collinearity, and area conservation.
