It is a rectangle that fits the given description.
They are the pairs of sides which are parallel.
Two examples of parallelograms with no right angles are a rhombus and a generic oblong parallelogram. A rhombus has all sides of equal length but can have angles that are not 90 degrees, while an oblong parallelogram has opposite sides that are equal in length and parallel but also lacks right angles. Both shapes maintain the properties of a parallelogram, including opposite sides being equal and parallel.
A rhombus.
square
A regular rectangle is a quadrilateral with 2 pairs of parallel sides, the pairs of parallel sides are the same length but they are different to the other pair of parallel sides. * * * * * The above definition is not specific enough: it could apply to any parallelogram. It is also a requirement that all its interior angles are right angles.
A TRAPEZIUM. Trapezia can be SYMMETRIC or ASSYMETRIC. That is Non-parallel sides can be of the same length or of different lengths/ intersext at different angles to the parallel lines.
Rhombus ; Internal 2 acute and two obtuse angles; four sides of equal length, opposite sides are parallel. Rectangle ; Internal angles are all 90 degrees(right angles), opposite sides of equal length and parallel. Adjacent sides are of different length.
A Rectangle
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.
A shape with opposite sides parallel and of the same length and four right angles is a rectangle.
A square has 3 sets of parallel sides of equal length AND all the angles are 90 degrees. A rhombus has 2 sets of parallel lines of equal length, but the angles aren't all 90 degrees.

It is a quadrilateral that has 2 parallel sides of different lengths and 2 sides of equal length with base angles being equal
