Microsoft interviews seeking to right triangle area: simple ...-Microsoft interview, right triangles-IT information

Find area of a right triangle? The title of even primary school students can appear in Microsoft interview questions, and the interviewer was also the subject of cruelty to cry, say it may surprise you, but it is a fact.

Recently one India students into Microsoft job interview process, only to find examiners gave him a geometry problem, why should calculate the area of a right triangle. The following figure, this is the end of a right triangle with up to 10 high 6. Who use the classic "high divide by 2 at the end of" formula quickly gave the answer, the area of the triangle is 30. However, the interviewer asked him again to stop.

Reviews again the interview data, decides that there are no errors, then confidently gave the same answer again. But the interviewer said, your answer is wrong.

Here, we should think of Yuan-the phrase, "this will be a catch."

The interviewer explained that as long as you follow the data above to calculate the results, the answer is wrong, because the triangle is no longer exist, high on the hypotenuse of a right triangle can not be more than half the length of the bottom edge. (The India guy psychological shadow area)

It turns out that this question was not investigated the interviewee's computing power or confidence, this question really studied the interviewee's judgment.

微软面试求直角三角形面积：看似简单… - 微软,面试,直角三角形 - IT资讯

求直角三角形面积？这种连小学生都会的题目竟然出现在微软面试题中，而且面试者还被这个题目虐哭了，说出来你可能不信，但这却是事实。

日前一名印度大学生杀入微软招聘面试环节，不料主考官给他出了一道几何题，就是要他计算直角三角形的面积。如下图，这是一个底长为10高为6的直角三角形。这名大学生用经典的“底乘高除以2”公式迅速给出了答案，该三角形面积为30。然而面试官却问他要不要再算一遍。

面试者重新核算了一遍数据后认为没有错误，于是再次自信地给出相同的答案。可是面试官却说，你的答案是错误的。

看到这里，大家应该想到了元芳的那句名言，“此事必有蹊跷”。

面试官解释称，只要你按照上面的数据算出结果，答案肯定是错的，因为这样的三角形实际是不存在的，在直角三角形中斜边上的高不可能超过底边长度的一半。（求此时印度小伙的心理阴影面积）

原来，这道题目并非考察面试者的计算能力或者自信心，这道题目真正的目的是考察面试者的判断能力。
