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.

By definition, all squares are parallelograms. Not all parallelograms, however, are squares. All rectangles and rhombuses are also parallelograms.

Yes. To be a trapezoid, a quadrilateral must have one pair of sides that are parallel. Since rhombuses are parallelograms, they are all also trapezoids, so a subset of trapezoids are rhombuses.

All rhombuses are paralleleograms. Rhombuses are parallelograms in which all four sides are the same length (and the opposite angles are congruent). Squares are rhombuses in which all four angles are right.

Quadrilaterals include trapeziums, trapezoids, parallelograms, rhombuses, rhomboids, rectangles, and squares.

A trapezoid can have 2 right angles. Parallelograms, rhombuses, rectangles, and squares can have 4.

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

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.

Yes Squares and Rhombuses are subsets of parallelograms.
