It almost looks like a scale model of a dangerous cliff side.

这幅画面看起来像等比例危险悬崖边的。

Two equal length sides, and one that's different, and " equilateral" has all three sides equal length.

等长的边， 还有一不同的边， “等边” 的三边都等长。

It was an adult, as could be seen from the six rows of teeth forming an isosceles triangle in its upper jaw.

这是一成年的鲨鱼，从它嘴里，在上上，有摆成等边三角形的六排牙齿，就可以看出来。

Actually, for that matter, since we made no  assumptions about the specific two sides we chose, it implies that any triangle is equilateral.

实际上，就这一点而言， 由于我们没有对我们选择的特边做出任何假设，因此这意味着任何三角形都是等边的。

The old man's route being along one side of an equilateral triangle, while Jim's was along two sides of the same, the former was at the point of intersection long before Hayward.

老人的路线是沿着等边三角形的一侧，而吉姆的路线是沿着等边三角形的侧，前者在海沃德之前很久就在交点处。

So this leaves us, somewhat disturbingly, with three different possibilities: All  triangles really are equilateral, that's just the truth of the universe, or you can use  Euclid-style reasoning to derive false results, or there's something wrong in the proof.

因此，这给我们留下了三种不同的可能性，这有点令人不安：所有三角形实际上都是等边的，这就是宇宙的真理，或者你可以使用欧几里得式的推理来得出错误的结果，或者证明中有问题。
