수락은 세상에서 가장 경이로운 것을 만드려고 한다
세상에서 가장 경이로운 것을 만드려면 몇가지 조건이 필요하다
1. '극한 가위질'을 5번 해야된다
2. 극한 가위질을 하고 난 뒤, 1/3을 자른다
이렇게 해서 남은 도형이 가장 경이로운 것이다
'극한 가위질' 이란
1. 어떤 가위를 가지고 정사각형 종이를 반으로 자르는 선을 40도 이상 간격으로 3개 긋는다
2. 그 선들을 자른다
3. 남은 도형을 가장 큰 정사각형으로 만든다
1) 가장 경이로운 것은 제일 처음의 정사각형의 종이의 최대 몇 배일까?
2) 가장 경이로운 것은 제일 처음의 정사각형의 종이의 최소 몇 배일까?
3) 극한 가위질 을 할때 3번을 빼고 어떤 한가지 조건을 더 추가하면 극한 가위질을 1번 했을때의 도형이 정삼각형일까?
*현재 1번 2번은 풀고 있습니다
