어떤식으로 풀어야하는건지 잘 모르겠습니다.. 8개구한대로 100개 구할수 있다는데.. 8개 최댓값은 알아냈긴 했다만 이걸로 어떻게 100개에 적용할지 잘 모르겠네요.. 도와주십쇼 :(

    8개에서의 배치를 거의 비슷하게 이용하시면 됩니다.. 다만, 선이 여러개 평행해지겠죠. 

    일반적으로 4m개의 선이 있을 때의 배치를 항상 아실 수 있어요.

    직각삼각형을 이루려면 일단 직교하는 선이 2개 있어야 겠죠?

    그다음 이 두 선과 각각 한 점에서 만나는 선이 있으면 작각삼각형이 나오겠죠.

    그러면 직교하는 두 선이 몇 쌍인지, 그다음 각각의 쌍과 만나는 선이 몇 개인지 구하면 쉽게 풀 수 있습니다.
