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.
The definition of a parallelogram is that it has four sides, the opposite sides are congruent and parallel, and opposite angles are congruent. This includes rectangles, squares, rhombuses, etc.The definition of a rhombus states that it is a parallelogram, but more specifically that all sides are congruent.So a rhombus is a parallelogram, but not all parallelograms 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.
A parallelogram has opposite sides parallel and equal in length, and opposite angles are equal. Squares, rectangles and rhombuses are all parallelograms.
A parallelogram is a quadrilateral (four-sided polygon) with two pairs of parallel sides. By definition, a parallelogram does not need to have all right angles. Think of rhombuses, which do not have any right angles, yet are parallelograms. Therefore, the answer is no.
