Summary

Description
English: Missing square puzzle animation. When the quadrilaterals are rotated about their centers they fill the space of the small square, although the total area of the figure seems unchanged. The apparent paradox is explained by the fact that the side of the new large square is a little smaller than the original one. A more complete explanation can be found in Missing square puzzle.
Français : Casse tête du carré manquant. Lorsque l'on tourne les quadrilatères, ils semblent combler le carré central, sans changer l'aire totale de la figure, ce qui est impossible. La résolution de ce paradoxe apparent est que la nouvelle figure est en réalité légèrement plus petite.
Slovenčina: Animacija manjkajočega kvadratka. Ko so štirje štirikotniki zavrteni okoli manjšega kvadrata, zapolnijo njegov prostor. Očitni paradoks se razloži z dejstvom, da je stranica večjega kvadrata malo manjša kot originalna
