有兩線段A、B如下 證明兩線段等長
A ꄠ B
───── ──────────
pf:
分別過A、B的左端點和右端點取兩條連線L1及L2交於P點
一線段是由無限多點所組成的
P A上有無限多個點,過P點做一線過任意A
//\\ 上一點,都可以在B上找到對應一點,故
/ / \ \ A上有n個點,B也就有n個點,此為一對一
/ / \ \ 映成。
/ / \ \ 則
────────── A A=nX=B
/ / \ \ A=B
/ / \ꄠ \
/ / \ ꄠ \
───────────────── B
L1 L3......Ln L2

下一輯來出五元硬幣跟十元硬幣一樣大好了
可能op過了吧 0.0?OP就不出了
本來想出子彈打不到我的題目說,但是道理跟龜兔一樣
當n到無限大時候差距=0 兔子就追到烏龜,子彈就打到我了
為了避免被子彈打到,還是跳過好了XD
