You can say that the proof uses nothing beyond elementary matrix theory, repeated use of the triangle inequality, and the pigeonhole principle.
你可以簡要地說其實証明就是初等矩陣?yán)碚?，三角不等式和鴿籠原理的運用。
For instance, it's also the square of the Euclidean norm on R2, the length of a two-dimensional vector, a part of the triangle inequality, and quite a bit more.
例如，R 2 的平方、二維曏量的長度、三角不等式等都存在勾股定理。
