Rhoumbus
Yes. A rhoumbus does have parellel lines
It may, but it's not required in order to be a rhombus.
a quadrangle is a rectangle,square,kite,rhoumbus,and other shapses that have four shapes.
No Every square is a rhombus Rhombii can be parallelograms, squares, or just rhombii as a shape.
No because although its 4 sides are equal in length its 4 interior angles aren't equal in measurement
Yes, a square is a rhombus. Don't get confused though, because a rhombus isn't a square. A square has 4 right angles, and a rhombus does not.
A quadrilateral is the term for a four sided polygon. It is the most general term. It does not imply anything about side lengths or angles being equal nor unequal. Some other answerers have stated that a trapezium (or trapezoid, depending or where you live) fits this description, but it is possible to have two sides (the non parallel sides) to have the same length and still be a trapezoid. But you can have a trapezoid (which only needs 4 sides and 1 pair of parallel sides) that fits the description above (4 sides none of which are equal length).
Well, honey, a rhombus is like that friend who always keeps it real - it has all sides equal in length. So, if you're looking for a shape with sides that are all buddy-buddy in terms of length, then the rhombus is your go-to guy. Just remember, don't mess with its sides, or it might just give you some attitude!
