「數學」好好做着幾何題,怎麼就變數論了呢?

這是來自於 2021 年 Euclid 競賽的最後一題,在前半題傳統的幾何題的誤導下,我們需要愉快地解一題看似幾何的數論題。整個題的思路並不複雜,但是用到了不少實用的結論。

At first glance this is nothing more than an innocent-looking geometric problem, but this last problem in 2021 Euclid Maths Contest surely speaks more than that. As it later turns out, this is a quite interesting number theory problem, which induces some handy tools for maths contests.
