Question 138224: Our teacher gave us these worksheets without explaining just to see what we know. There is one question that says solve for the variables.There's a parallelogram, on the left it has 2y-7.On the right it has 9. On the bottom it has 23. And on the top it has 3x+2. Can you explain this to me please

Question 151452: 1) ABCD is a parallelogram if AB = 2 AD and P is the midpoint of AB.prove that angle CPD = 90.
2) If the diagonal PR and QS of a parallelogram PQRS are equal, prove that PQRS is a rectangle.
3) PQRS is a parallelogram. PS is produced to M so that SM = SR and MR is produced to meet PQ produced to N. Prove that QN = QR.

Question 158027: I would mean alot to me if someone could help me out on this problem
I did find a smiliar question to mine, but could really understand how i would get the answer.
Consider the points P(10,2),Q(1,11), and R(-8,2) on a coordinate plane. Where must the point S be located so that the quadrilateral PQRS is a square?
i found the slope of PQ i got -1
I found the slope of QR i got 1
then what do we do after gettting the slope
please help
