小一數學題

bbmammy

我發現上下學期，數學都有一些方向的問題。如球體在錐體的哪邊(e.g. O   ^) 答案是左邊，以eyes 望到在左。

但有時問郵箱在燈柱的哪邊?燈柱在小明的哪邊?全部答案出剛巧相反。

請問幾時以眼望的左右方為答案?

  

估唔到被小一問題難倒如何分左右！這次真如張國榮所唱"竟調亂左右"

bbmammy ,

{ o ^} 答案應是在左邊, 正確, 這些題目不是問圖中，所以就要eye去看

而第二條問題則是問圖內，如什麼在xx 那裏，通要跟據圖內情況去判斷左右

Both of them are pictures, so how to do ???

bbmammy,

It is quite straight forward. timtim-mame is right. All questions must come with a "ICTURE" in book, if not, how can they ask you in book ? If those question begin with "在圖中" (usually asked about some objects in the picture (物件/人物, 如小明或燈柱)), then decide from that object's point of view. If the question does not begin with "在圖中" (usually about some shapes or 圖案), then decide with your eyes.

Make it simple:

First, to clarify the subject. All questions are subjective. So if the subject is the observer (you), then define in your own side.

While question 2 clearly ask what is the side (left or right) of the things to the lamp post. the subject is the lamp post. so decide as you are the lamp post.

Thanks for your (both of you) explanation.  Now, I have more understand on it.
