Are all rombi parallelograms?
Yes, all rhombi are parallelograms. A rhombus is, by definition, "a parallelogram in which all of the sides are the same length."
How can you convince me that a rhombus is a parallelogram but a parallelogram is not a rhombus?
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).
What has four sides and two pairs of sides the same length?
Shapes with 4 sides are called quadrilaterals. If all the sides of the shape have the same length, then there are two options for specific quadrilaterals. These are squares or rhombuses. If the pairs of sides are not the same length as each other, then there are two alternate options for the shape. These are rectangles and parallelograms.
What is a long parallelogram?
It is important to know the different parallelograms. A long parallelogram is a parallelograms whose sides are long in length.
What shape is a square but not a parelellogram?
No shape is a square but not a parallelogram as all squares are parallelograms: All parallelograms have opposite sides parallel and of equal length, and opposite angles are equal. All squares have opposite sides that are parallel and of equal length, and opposite angles are equal; thus all squares are parallelograms. However, all squares also have all angles equal to 90o and all four sides equal, but some parallelograms have angles not all 90o and/or not all four sides of equal length; thus not all parallelograms are squares.
Are parallelograms rhombuses?
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.
Are all rombi parallelograms?
Yes, all rhombi are parallelograms. A rhombus is, by definition, "a parallelogram in which all of the sides are the same length."
How is a rhombus different from a paralleogram?
In a rhombus all four sides are of equal length, while in a parallelogram opposing sides have the same length. Thus all rhombi are parallelograms, but all parallelograms are not rhombi.
How are parallelograms and rhombus' different?
Adjacent sides of a parallelogram may be of different length. In a rhombus all four sides must be of the same length.

Two parallelograms have pairs of sides that are three feet long and two feet long one of the parallelograms is a rectangle and the other is not Which has a bigger area and why?
I think they are the same length because they have equal sides and the area would not change.
Do parallelograms have to be squares?
No.Parallelograms have two pairs of parallel opposite sides; they do not have to be the same length.The opposite angles of a Parallelogram are equal; they do not have to be 90oA square is required to have all sides equal (opposite sites will be parallel) and all angles 90o (opposite angles are the same)Thus all squares are parallelograms, but only some parallelograms are squares.A rhombus is a parallelogram which has all sides the same length.
What is a long parallelogram?
It is important to know the different parallelograms. A long parallelogram is a parallelograms whose sides are long in length.
Are some parallelograms are kites?
In a parallelogram the opposite sides are equal in length. In a kite two pairs of adjacent sides are equal in length.
What shape is a square but not a parelellogram?
No shape is a square but not a parallelogram as all squares are parallelograms: All parallelograms have opposite sides parallel and of equal length, and opposite angles are equal.

A quadrilateral having both pairs of opposite sides parallel?
A square if sides are equal. Otherwise a rectangle. A parallelogram. Rectangles are special cases of parallelograms. Parallelograms need not have all angles equal. * * * * * No. A parallelogram if the sides are of unequal length (rectangle if the angles are 90 degrees) or rhombus if all four sides are of the same length (square if the angles are 90 degrees).
