The Missing Square Puzzle: A Classic Geometric Paradox Explained #2258199 (License: Personal Use)

This image illustrates the well-known “missing square puzzle,” where four geometric pieces-two right triangles and two irregular quadrilaterals-are arranged to form a large right triangle. In the top configuration, the pieces fit perfectly; in the bottom, they appear to form the same triangle but leave a 1×1 square gap. The illusion arises because the hypotenuse is not truly straight: the red and teal triangles have slightly different slopes (3/8 vs. 2/5), causing a barely perceptible bend that accounts for the extra area.
