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 parallelogram has the following properties:Two pairs of parallel sidesOpposite sides equalOpoosite angles equalDiagonals bisect each otherTherefore in order for a quadrilateral to be a parallelogram it has to have all of these same properties and in regards to your question it must also have all sides the same length.The answer is: square and rhombus
A parallelogram can be a square, but never can a square be a parallelogram. A square is defined as having all four sides the same and all four right angles. A parallelogram has to have two pairs of parallel sides.
A rhombus
A rhombus
not all of the sides, but 2 pairs of congruent sides
No.
a square
A square.
Yes
No. But the opposite sides do - in pairs.
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.
a parallelogram who's sides measure the same is called a rhombus :^>
A square.
A rhombus
A rhombus.
It is, if all four of its sides are the same length.
