In the xy-coordinate plane, what are the x-coordinates of the four vertices of square JKMN ?
(1) J and M are on the x-axis, and K and N are on the y-axis.
(2) The center of the square is at the origin.

Target question: What are the x-coordinates of the four vertices of square JKMN ?
When I SCAN the two statements (
always scan the statements before performing any calculations!), I see that neither statement provides any information about the
size of the square.
So, I’m going to head straight to……
Statements 1 and 2 combined
There are infinitely many squares that satisfy BOTH statements. Here are two:

Since the 4 vertices of the smaller square are different from the 4 vertices of the larger square, we can conclude that there is no way we can answer
target question with certainty
So, the combined statements are NOT SUFFICIENT
Answer: E
