Question

In the figure on the right, STWC space is a square centered at the origin with side length 2a What are the coordinates of the vertices?

Answer 1

D. S(-a, -a), T(-a, a), W(a, a), Z(a, -a)

Explanation:

Point S is in the 3rd quadrant, where both coordinates are negative. That eliminates choices A and B.

The distance between points is 2a, so the distance from a corner point to either axis is "a". That is, the magnitude of any coordinate value is "a", not "2a." That eliminates choice C.

Remaining is the correct choice: D.
