They both have 4 sides
They both have 4 interior angles that add up to 360 degrees
They both have 2 diagonals
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
Are all rectangles parallelograms
Rhombi (or rhombuses)
squares, rectangles, rhombuses
By definition, all squares are parallelograms. Not all parallelograms, however, are squares. All rectangles and rhombuses are also parallelograms.
parallelograms, rhombuses, & hexagons
All rhombuses are parallelograms because to be a parallelogram you only have to have four sides and have opposite sides congruent.
