A parallelogram requires that opposite sides are parallel and of the same length; it is not a requirement that all four sides are of the same length. A rhombus requires that opposite sides are parallel and all four sides are of the same length. It is possible that a parallelogram can have all four sides of the same length; when it does it now fulfils the requirements of a rhombus, and so is a rhombus. Thus a rhombus is a type of parallelogram (all rhombuses are parallelograms), but there are parallelograms which are not rhombuses (those where there are two sides of one length (opposite and parallel) and the other two sides of a different length).
A Rhombus
A parallelogram is a four sided quadrilateral and it has 2 same congruent sides. The top and the bottom.
Rectangle, parallelogram
If a parallelogram has all four sides the same length it's called a square.
No.

No. But the opposite sides do - in pairs.
A square.
A rhombus
A square or a rhombus.
A Rhombus
All four sides of a rhombus are the same length. In a parallelogram there are two pairs of sides with equal lengths but one pair is different from the other pair.

Rectangle, parallelogram
In a rhombus each of the sides is of the same length whereas in a parallelogram, each pair of opposite sides is of the same length but the two pairs are different.
No. A rhombus is a special case when all four sides are of the same length. A parallelogram must have opposite sides of equal length but adjacent sides can be of different length.
