This is called a rhombus.
A parallelogram is a four sided quadrilateral and it has 2 same congruent sides. The top and the bottom.
It is, if all four of its sides are the same length.
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.
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 is a shape or figure with Four sides that have one of the opposite sides of one side the same lenth. So a square IS a parallelogram.
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).
yes * * * * * No, it is not. A rhombus is a special kind of parallelogram. In a rhombus all four sides are of the same length: that is not necessarily the case for a parallelogram.
Technically it is because a rhombus is a parallelogram that has four sides of equal length in the same way that a square is technically a rectangle that has four sides of equal length.
A rhombus is a kind of parallelogram. All four of its sides are of the same length.
A parallelogram is a rhombus only if all four of its sides have the same length.
It could be either of the following: * Rhombus - A parallelogram with four sides of equal length. * Square - A parallelogram with four sides of equal length and four angles of equal size (right angles).
If a parallelogram has all four sides the same length it's called a square.
