A parallelogram is a quadrilateral four sided figure with two pairs of parallel opposite sides A rhombus is a parallelogram all of whose sides have the same length A Explain how two nonzero and nonparallel vectors in R2 two dimensional space can be used to determine a parallelogram B Explain how one nonzero vector in R can be used to determine a rhombus with one side on the z axis C Draw a picture of the rhombus with one side on the ar axis determined by the vector 5 2 Then show that the diagonals of this rhombus intersect at a right angle D Do the diagonals of any rhombus intersect at a right angle Explain
