Prove that the quadrilateral defined by the points A (-2,2), B (6,5), C (4,0) , and D (-4,-3) is a parallelogram.

when we get the length of these sides we see that each two sides that are in front of each other are equal.

Step-by-step explanation:

that means it could be either rectangle or parallelogram. (with that said when we draw a perpendicular from one side to the other we see that we need a extra line meaning that none of our sides are perpendicular to each other) that leaves only parallelogram.

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
