[ ваш заказ * отмена не возможно. товар ]:2 неделя ~4 неделя . доставка ( тот, кто спешит пожалуйста воздержитесь.) | [книга@. информация ]128 страница 201*251mm язык :English 612g ISBN:9781402716669 | [книга@. содержание ]A colorful square dissected into four parts with hinges marked in black. If you leave the blue piece fixed and swing the others around their hinges a new shape will emerge. Can you guess just by looking what it will be? This is just one of the tricky geometrical gems that will make a puzzler*s mind work overtime. Try drawing a set of variously shaped polygons using only a compass and a ruler (no measuring allowed!) figuring out which of two sculptures is bigger (logic alone won*t give you the answer) and lots more. |
