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

幅画面看起来像比例危险悬崖的模型。

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

两条长的， 还有条不同的， “” 的三条都长。

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

是条成年的鲨鱼，从它嘴里，在上上，有摆成三角形的六排牙齿，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，点而言， 由于我们没有对我们选择的特定两条做出任何假设，因此意味着任何三角形都是的。

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.

老人的路线是沿着三角形的侧，而吉姆的路线是沿着三角形的两侧，前者在海沃德之前很久在交点处。

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，给我们留下了三种不同的可能性，有点令人不安：所有三角形实际上都是的，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。
