Could be be both.
AB, BC, CD and DA have the magnitudes:
square root of 32, square root of 12, square root of 32, square root of 12
What kind of quadrilateral?
A rectangle or parallelogram?
Confused bc dont know the angles? A rectangle has all 90degree angles?
Thanks in advanced..
That is a parallelogram because opposite sides are of equal length. But such a parallelogram can have any angles (Imagine the side "pinned" together and free to rotate around the pin- You can tilt the parallelogram from a rectangle to almost a straight line).
