No. But the opposite sides do - in pairs.
A square. Or an equilateral parallelogram.

are all the sides are equal the same length, its a parallelogram because the all the sides will never meet.
That is called a rhombus.
If a parallelogram has all four sides the same length it's called a square.
a parallelogram who's sides measure the same is called a rhombus :^>
Not necessarily. Usually only the opposite side are of equal length. If all 4 sides are of the same length, the parallelogram is [also] called a rhombus.
No.
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).
The definition is that opposite sides are parallel. That doesn't tell is they are same length or not. Should a parallelogram be of the special case of having it, then it is called rhombus, or in the case that also all angles are 90°, it's called a square.
No. But the opposite sides do - in pairs.
