Logical geometry

This task is about geometric properties of quadrilaterals.
A quadrilateral is a two-dimensional shape with four straight sides. 
Five quadrilaterals are shown below.

Parallelogram
(2 pairs of parallel sides,
all sides equal length)

Square
(2 pairs of parallel sides,
all sides equal length, all angles 90o)

Rectangle
(2 pairs of parallel sides, 
opposite sides equal length, all angles 90o)
 
Following are statements about quadrilaterals. One statement in each pair is true and the other is false.
