Triunghiul de monede de 50 bani

Proposed by GabiOffline
(2 comments)2.496 times displayed

Sa zicem ca avem un sac de monede de 50 de bani. Cu ele, construim o figura geometrica astfel: punem intai o moneda, apoi sub ea altele trei, pe randul urmator inca cinci, apoi sapte.

Intrebare: puteti transforma acest triunghi intr-un patrat? Daca da, cate monede veti muta ?

Intrebarea numarul 2 este la fel ca prima, dar consideram ca mai adaugam inca trei randuri: 9, 11, 13.
