来个数学笑话steemCreated with Sketch.

in #steempress5 years ago (edited)

前面几篇写了好几个关于水的笑话,都是属于化学类的。实际上笑话是不分学科的,这篇来一个数学笑话。

Q: Why are obtuse angles so depressed?
A: Because they’re never right.

翻译前先解释一下专业术语。obtuse angles的意思是钝角,就是大于90度小于180度的角。所以这个笑话翻译过来就是:

为什么钝角很沮丧呢?
因为它们从来都不对。

啥意思?为啥是钝角不right?要看懂这个笑话,得知道啥是right angel。这里的right可不是“正确”的意思,在数学里right angle的意思是直角。写到这里,这个笑话就看明白啦:钝角沮丧,因为它不是直角。

这个笑话就解释完了,笑过之后学到点东西才是最重要的。从这个笑话中,我们学到了这样几个词:obtuse angles的意思是钝角,right angle的意思是直角。最后,再来一点补充知识愉快的结束这个笑话。

锐角的英文是acute angle。
