A shape with no right angles and one pair of parallel lines would be called a trapezoid in the USA, and a trapezium in Britain.

trapezoid
A trapezoid has 4 sides, 2 right angles and 1 pair of parallel lines
A shape that has exactly 4 sides, 2 right angles and one pair of parallel sides is a rectangle. ~T
A right trapezium.
A trapezium (has only one pair of unequal parallel lines).
a tetrahedon
a square or a trapezium
A trapeziod.
square
If you mean shape there is no such shape. if a 4 sided shape has 2 right angles it MUST be either a square or a rectangle, in which case there are actually 4 right angles and 2 pairs of parallel sides. =)
A trapezoid can have 2 right angles and 1 pair of opposite parallel sides of different lengths. The 4 interior angles will add up to 360 degrees.
