The diagonals of a parallelogram are given by A = 3i -4j -k and B = 2i +3j - 6k. Show that the parallelogram is a rhombus and determine the length of its sides and its angles.

Dear Student

A.B= dot product of A and B = 0
hence, A and B are perpendicular
Since,Diagonals are perpendicular,The given shape is rhombus as it is the property of rhombus that the diagonals of rhombus bisect perpendicularly

Thanks
