can you help me solve this? please show me how

116. In the xy-plane, the points (c,d), (c,-d), and t three vertices of a certain square. If c

1st vertex = (c,d) which is in 2nd quadrant where x is negative and y is positive.

2nd vertex = (c,-d) which is in 3rd quadrant where both x and y are negative.

3rd vertex = (-c,-d) which is in 4th quadrant where x is positive and y is negative.

So 4th vertex must be in 1st quadrant that is both x and y are positive. So answer is (3,5) (ANSWER)
