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.

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 parallelograms and rhombus the same think?
No. All rhombi (rhombuses) are parallelograms but all parallelograms are not rhombi.
What is the difference between a rhombuses and a rectangle?
A rectangle is correct; a rhombuses is not.
What shapes are also parallelograms?
squares, rectangles, rhombuses
Which three quadrilaterals have obtuse angles?
parallelograms, rhombuses, & hexagons
Are parallelograms rhombuses?
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.
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.)
What parallelograms are not rectangles?
rhombuses
Are all rhombuses also rectangles?
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.
Are parallelograms and rhombus the same think?
No. All rhombi (rhombuses) are parallelograms but all parallelograms are not rhombi.
Can some rhombuses be parallelograms?
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
What is the difference between a rhombuses and a rectangle?
A rectangle is correct; a rhombuses is not.
What parallelograms don't have right angles?
Rhombi (or rhombuses)
Why are all squares rhombuses?
Are all rectangles parallelograms
What shapes are also parallelograms?
squares, rectangles, rhombuses
Some parallelograms are squares?
By definition, all squares are parallelograms. Not all parallelograms, however, are squares. All rectangles and rhombuses are also parallelograms.
Which three quadrilaterals have obtuse angles?
parallelograms, rhombuses, & hexagons
