问题
In the figure above, ABCD is a square. What are the coordinates of point B?
选项
A、(-4,2)
B、(-2,4)
C、(-2,6)
D、(4,-6)
E、(6,-2)
答案
C
解析
左上面的图形中,ABCD是一个正方形,B点的坐标是多少?
解:本题的正确答案为(C)。设B点的坐标为(x,y),由ABCD是一个正方形,可知其对角线互相垂直平分,设A点与C点连线的中点坐标为(x’,y’),则x’=(-6+4)/2=-1, y’=(0+2)/2=1。即中点为(-1,1),也即B与D的中点的坐标为(-1,1),从而可以得出:-1=(0+x)/2, 1=(-4+y)/2 → x=-2,y=6,即B点的坐标为(-2,6)。
