All rhombuses are parallelograms because the definition of a parallelogram is that opposite sides equal and opposite angels equal. A rhombuses definition is that all side equal and opposite angels equal. So the rhombus fits the definition of a parallelogram.

Are parallelograms and rhombus the same think?

No. All rhombi (rhombuses) are parallelograms but all parallelograms are not rhombi.

Can a quadrilateral be a parallelogram and a rhombus?

Yes. All rhombuses are parallelograms, but the reverse is not true. (I.e. there are parallelograms which are rhombuses and there a parallelograms that are not rhombuses. -- Just like Every bus has wheels but not everything with wheels is a bus.)

Are all rhombuses also rectangles?
