Answer:
(3.2) ; (1,2) -> (3,-2)' ; (1,-2)'
Explanation:
This question is incredibly written incorrectly since in order to form a square from those few points you're required to reflect the points over the x-axis to form a square.
Reflection over x-axis transformation: (x,-y)
(3.2) ; (1,2) -> (3,-2)' ; (1,-2)'
Even that makes a rectangle. :(
However, quadrilaterals are quadrilaterals.
