Hi guys, I'm about to have a test on vectors and am looking for some geometric proof questions surrounding:
Prove geometric results and construct proofs involving vectors in two dimensions, including:
– the diagonals of a parallelogram meet at right angles if and only if it is a rhombus
– the midpoints of the sides of a quadrilateral join to form a parallelogram
– the sum of the squares of the lengths of the diagonals of a parallelogram is equal to the sum of the squares of the lengths of the sides

thanks in advance it would rly help
