这个定理描述很简单,证明也很简单,紫檀数学牛蛙都可以玩一玩(不要告诉孩子答案,让他们自己证明):

Say there are more than one finite number of points on a Euclidean plane, and they are not falling on a single straight line.  Proof that there exists a straight line that goes through only two of those finite points.

Deepseek R 的证明(昨天在Android tablet app上问的):

虽然有错但离正确的证明只差一点点。

ChatGPT V2 (免费版)的证明:

我同事问了付费版的ChatGPT o1,更不靠谱,问两遍都是胡乱证明。

我今天在 Deepseek R 网页版又问一遍,完全错了。

简单证明见这里:Kelley's proof
