Summary

Description
English: Animation of Missing square puzzle. The hole results because the two triangle pieces do not have the same ratio: the blue triangle is 2:5, while the red triangle is 3:8. The initial shape of the complete puzzle is not a triangle, but a quadrilateral, since what appears to be the hypotenuse is actually bent.
Deutsch: Animierte Darstellung des Fehlenden-Quadrat-Rätsels. Das fehlende Quadrat ergibt sich, weil die zwei Dreiecke nicht dasselbe Seitenverhältnis aufweisen: beim blauen Dreieck beträgt es 2:5, während es beim roten Dreieck 3:8 beträgt. Die anfängliche geometrische Figur des Puzzles ist kein Dreieck, sondern ein Viereck, da die scheinbare Hypotenuse nicht gerade, sondern gebogen ist.

Čeština: Animace řešení hlavolamu Záhada chybějícího čtverce. Prázný čtverec vzniká proto, že dva trojúhleníkové díly nemají strany ve stejném poměru: modrý trojúhelník má poměr 2:5,zatímco červený má 3:8. Původní tvar celého puzzlu není trojúhelník, ale čtyřúhelník, a to co se jeví jako přepona je ve skutečnosti zahnutá křivka.

Русский: Оптическая иллюзия, связанная с «появлением» лишней клетки при перестановке синего и красного треугольников. Секрет иллюзии в том, что начальная и конечные фигуры являются вовсе не треугольниками, а четырёхугольниками.
中文（简体）：失踪的正方形动画。出现洞是因为两块三角形不是同一个斜率：蓝色三角形是 2:5，红色三角形是 3:8。最初完整的图形并非三角形，反倒是四边形，看起来是斜边实际上有弯曲。
