as matter of fact, what autocad did is exact number with no errors.

yes. you can do any regular polygon as you want. but how do you know the accuracy of the auto-cad? how can you check? with this classic method, you can check if you want. But most time it is not necessary.

if you use autocad, you can make any 边形 you want in less than 5 seconds.
your 25 边形 looks almost like a circle.
谢谢指出错误，有些不好意思啊，两个2漏了平方了。
