Answer:
The vertices are (7,6), (-7,6), (-7,-7) and (7,-7).
Explanation:
The vertices are the coordinates of each corner of the square.
In this drawing, we have one vertex in each quadrant.
The vertex in the first quadrant has a x-coordinate of 7 and a y-coordinate of 6, so let's call this vertex A = (7,6).
The vertex in the second quadrant has a x-coordinate of -7 and a y-coordinate of 6, so let's call this vertex B = (-7,6).
The vertex in the third quadrant has a x-coordinate of -7 and a y-coordinate of -7, so let's call this vertex C = (-7,-7).
The vertex in the fourth quadrant has a x-coordinate of 7 and a y-coordinate of -7, so let's call this vertex D = (7,-7).
So the vertices are (7,6), (-7,6), (-7,-7) and (7,-7).
