Homework Statement
Use Cartesian vectors in two-space to prove that the line segments joining midpoints of the consecutive sides of a quadrilateral form a parallelogram.
Homework Equations
The Attempt at a Solution
the only thing I can think of is; the only way joining the midpoints of the consecutive sides of a quadrilateral will form a parallelogram is if the quadrilateral IS a parallelogram in the first place...I'm pretty sure this is not the correct answer so any guidance is greatly appreciated...THANKS!
