The Puzzle
Tangramagic title

Paradoxical figures
Using the seven Tangram pieces, form first the white figures in the table below, and then their black counterparts. In both cases, you have to use all seven pieces (see animated tutorial opposite). Try to explain why a small black triangle is missing in the black figure!

Constructions paradoxales
Formez avec les 7 pièces du Tangram une des figures du tableau ci-dessous, en blanc. Puis, celle opposée, en noir. Expliquez pourquoi il manque une pièce à cette dernière!

Costruzioni paradossali
Con tutti e 7 i pezzi del Tangram devi costruire prima una delle figure illustrate in bianco, e poi la sua controparte in nero. Le due figure sono apparentemente uguali in tutto tranne in un particolare che è assente nella seconda figura. Puoi spiegare perché?
