For parallelograms, the lengths of each side in one pair of opposite sides don't have to be equal to the lengths of each side in the other pair, so, even though two sides are always equal in length, all 4 sides are only sometimes equal in length (as with a square). A rhombus always has all 4 sides equal in length. A rhombus (like a square or a diamond) is a parallelogram, but not all parallelograms are rhombuses.
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.)
No. All rhombi (rhombuses) are parallelograms but all parallelograms are not rhombi.
A rectangle is correct; a rhombuses is not.

Some parallelograms are rhombuses, but all rhombuses are parallelograms. A parallelogram is a rhombus if and only if all of it's sides are the same length.
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.)
rhombuses
No. Rhombuses that are also rectangles are called squares. Rhombuses are parallelograms with 4 equal sides, while rectangles are parallelograms where all the angles are right.
No. All rhombi (rhombuses) are parallelograms but all parallelograms are not rhombi.
Some rhombuses can be parallelograms. It all depends on the direction of the sides. A diamond is a rhombus that is not a parallelogram A square is a rhombus that is a parallelogram
A rectangle is correct; a rhombuses is not.

Rhombi (or rhombuses)
By definition, all squares are parallelograms. Not all parallelograms, however, are squares. All rectangles and rhombuses are also parallelograms.
