I have no clue where to start on this question.
Use Cartesian vectors in two-space to prove that the line segments joining midpoints of the consecutive sides of a quadrilateral form a parallelogram.
Atm all i can deduce from the information is that vectors 2A+2B+2C+2D=0 therefore midpoint vectors A+B+C+D=0 and to prove that it is a parallelogram A+B//C+D and vector A+C//B+D
