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模型。

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

这是一条成年的鲨鱼，从它嘴里，，有摆成等边三角形的六排牙齿，就可以看出来。

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

两条等长的边， 还有一条同的边， “等边” 的三条边都等长。

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， 既然我们对选定的意两边没有何假设，这暗示了何一个三角形都是等边的。

In the first course, there was a shoulder of mutton cut into an equilateral triangle, a piece of beef into a rhomboides, and a pudding into a cycloid.

第一道菜里，有一块切成等边三角形的羊肉，一块切成菱形的牛肉，还有一块成旋轮线形状的布丁。

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两侧，前者海沃德之前很久就交点处。

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.

所以这让我们有点安地面对三种同的可能性：所有的三角形实际是等边的，这就是宇宙的真相，或者你可以使用欧几里得式的推理得出错误的结果，或者证明中有什么问题。
