A quadrilateral has four sides and four vertices but no sides need to be parallel although they can be.

a rhombus
it is a trapezium
That quadrilateral is known as a 'parallelogram'.
to me a quadrilateral always has parallel sides
It is not possible to have a quadrilateral with four parallel sides - this would bea series of four parallel lines that do not intersect.A quadrilateral with four sides of equal length is a rhombus, however.And a quadrilateral with 2 pairs of parallel sides is a parallelogram.

I am a rhombus. I don't need to prove that my opposite sides are parallel. If I'm a quadrilateral with four sides that are the same length, then I am definitely a rhombus.

Yes, a parallelogram is always a quadrilateral. By definition, a parallelogram is a four-sided figure (quadrilateral) with opposite sides that are parallel and equal in length. Therefore, every parallelogram meets the criteria of being a quadrilateral.
A quadrilateral with 4 right angles and opposite sides that are parallel can be either a rectangle if the adjacent sides are of different length or a square if the adjacent sides are of the same length.
yes, parallel sides, and equal length sides.
