HIJK is a parallelogram because the midpoint of both diagonals is
(1 , 0), which means the diagonals bisect each other
Step-by-step explanation:
If (x , y) is the mid-point of a segment whose end points are  and
  and   then,
  then,
In a parallelogram, its diagonals intersect each other at their mid-points 
that means its diagonals bisect each other
∵ HIJK is a quadrilateral
∵ HJ and IK are its diagonals
∵ H = (-2 , 2) 
∵ J = (4 , -2)
- Find the mid point of HJ  
∵  
 
∴  
 
∴ 
∴ The mid-point of HJ is (1 , 0)
 ∵ I = (4 , 3) 
∵ K = (-2 , -3)
- Find the mid point of IK  
∵  
 
∴  
 
∴ 
∴ The mid-point of IK is (1 , 0)
∵ The mid-points of HJ and IK are equal
∴ HJ and IK bisects each other
∴ HIJK is a parallelogram because its diagonals bisect each other
HIJK is a parallelogram because the midpoint of both diagonals is
(1 , 0), which means the diagonals bisect each other
