Note:
(a) parallelogram (n): "a quadrilateral with opposite sides parallel and
equal"
* quadrilateral (n): "a polygon of four sides"
(b) bisect (vt): "to divide into two usually equal parts" |

minute is obviously not qualified to teach in middle schools - maybe OK in a
Negro school... I surely would not want this kind of people to teach my
kids.

发帖数: 6973 | 4 Well, my humble confession.
I was good at mathematics back in Taiwan. HOWEVER, I am rusty now. Very much
so. I even forgot a 30-60-90 triangle. So it took me about five minutes (at
least) this morning.

True, I learned it at junior high in Taiwan, but that was decades ago.

I agree with you that the question should be solved in a minute. A
standardized test usually allows you that much time for each question. That
is why I knew I flunked the test when it took me more than a minute.

发帖数: 1397 | 8 Sure, your candidness is appreciated. :-)
I actually tested three 8th graders yesterday with the problem, one black
girl, two white boys.
The black girl had no clue how to solve it whatsoever;
The first white boy gave up after about 2 minutes;
The second white boy, who is a good one (evidenced by getting admission to
Bronx Science), solved it after 4 minutes.
All students are from a very good public school in Manhattan.
