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.
