A shape with parallel sides but no right angles is called a parallelogram
It is an irregular pentagon.
No shape does. If it has 4 sides and one pair of parallel lines it cannot have only 1 right angle, it must either have: 1) 2 right angles, 1 acute acute and 1 obtuse angle; or 2) no right angles, 2 acute angles and 2 obtuse angles; in which case it would be a trapezium (trapezoid).
A trapezoid would fit the given description providing its other two angles are acute and obtuse with all four angles adding up to 360 degrees.
Does the shape you are looking for look something like this <> if the lines met if so the shape you era thinking of is a parallelogram A rhombus is a parallelogram with all of the sides the same length
pentagon

a trapezium

A trapezoid has 4 sides, 2 acute and 2 obtuse angles, and only one pair of parallel sides
a diamond does. There are two obtuse angles in it.
A parrelellegram
a diamon, pentagon, nonagon, heptagon
A parallelogram or a rhombus
this shape would be a rhombus
A trapezoid perhaps?
