Question 143178: parallelogram abcd is not a rectangle the points of a b c and d are (-2,2) (6,5) (4,0) (-4,-3) prove that paralleogram is not a rectangle Answer by vleith(2983) (Show Source):
You can put this solution on YOUR website! All you need to do is prove the line segments that create one of the vertex are not at right angles.
Find the slope of one side segment, then find the slope of the segment that intersects at that vertex. Then show the products of those slopes is not equal to -1.
If you can show that, then the shape cannot be a rectangle.
