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.

第道菜，羊肩肉成等边三角形，牛肉成菱形，布丁成摆线。

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.

老人路线是沿着等边三角形，而吉姆路线是沿着等边三角形两，前者在海沃德之前很久就在交点处。
