Question

Let P, Q, R and S be the points on the plane with position vectors respectively. The quadrilateral PQRS must be a

Options

A.parallelogram, which is neither a rhombus nor a rectangle
B.square
C.rectangle, but not a square
D.rhombus, but not a square

Solution


Evaluating midpoint of PR and QS which
gives M ≡ , same for both.




Hence, PQRS is a parallelogram but not rhombus or rectangle.
