please double check coordinates. they create non-square.vscid wrote:On the coordinate plane (6, 2) and (0, 6) are the endpoints of the diagonal of a square. What is the distance between point (0, 0) and the closest vertex of the square?

It will be a square where the sides are NOT parallel to either of the axes.
Cheers.

Why do you think the coordinates result in a non-square?tom4lax wrote:Am I missing something, or do those coordinates result in a non-square quad.?
The GMAT is indeed adaptable. Whenever I answer RC, it proficiently 'adapts' itself to mark my 'right' answer 'wrong'.
endpoints of diagonal (0,6) and (6,2) = difference in x values of 6 and y values of 4, sides aren't of same length. However, if the sides aren't parallel to the axis, then possibly it is a square. I just don't know how you would find these points?

Don't know a quick way to find.. It took me almost 10 min to reach to the solution...
The two points are (6,2) and (0,6)
The length of diagonal = sqrt(52)
Length of the side = sqrt(26)
Now the two points we know and the length we know so using the formula sqrt( sqr(x1-x2) + sqr(y1-y2)) we can get two equations..
Let the 3rd point in square be (x,y)
For (6,2) == x^2 + y^2 -12x - 4y + 14 = 0 ------- 1
for (6,0) == x^2 + y^2 -12y + 10 = 0 ------------- 2
subtract one from other then we get 3x - 2y = 1
x = 1/3(1+2y)
Sub x in 2
we get y^2 - 8y +7 = 0
so values of Y = 1 , 7
then value of X = 1, 5
(1,1) is nearer to (0,0)
so the distance = sqrt(2)

Nowhere it is mentioned that the sides are parallel to the axis.tom4lax wrote:endpoints of diagonal (0,6) and (6,2) = difference in x values of 6 and y values of 4, sides aren't of same length.

Almost the same way, aspireGMAT did.tom4lax wrote:Right, thanks, I realize that now.
How did you solve the question?
