No, because a parallelogram is not always a rectangle.

No.  Ainsley is not correct.
Her remark is incorrect.
She has it exactly backwards.

A parallelogram is only a rectangle if it happens to have
right angles in it, but most of them aren't.

A rectangle is ALWAYS a parallelogram, because its
opposite sides are parallel. 
A rectangle is a special kind of parallelogram ... one with
right angles in it.
If you stack too many books on top of a rectangle, and it
starts to bend and it kind of leans to one side, then it
stops being a rectangle, but it's still a parallelogram.
