Explanation:
The quadrilateral will be a parallelogram if the diagonals bisect each other. That will be the case if the sums of their end-point coordinates are the same.
A + C = (-3, 6) +(9, -9) = (6, -3)
B + D = (6, 0) +(0, -3) = (6, -3)
Both diagonals have their midpoint at (3, -1.5), so the diagonals are mutual bisectors. The figure ABCD must be a parallelogram.
___
The midpoint of AC is (A+C)/2 = (6, -3)/2 = (3, -1.5).
X=2 because (-8x+117)=101 if x=2 -8*2=-16. -16+117=101
A rectangle or a parallelogram is a polygon with only 2 congruent sides and 2 congruent angles.
I think it’s the first answer! Good luck!
