An irregular pentagon.
I'm sorry there is no possible way to make a parallel lines form a right angle in any sort of shape unless u where to bend one of the lines in which case they would no longer be parallel.
a right angle triangle.
The rhombus.
In plane geometry, a shape with four sides, two of which are parallel and have the same length, cannot have a reflex angle.
That is called an angle.
Right angle triangle, yup that's right
A trapezoid!

A rectangle (i.e. a square or an oblong)
A regular pentagon does not have parallel or perpendicular lines. Some other possibilities include, but are not limited to:a circlean ovalan equilateral triangle or any triangle that is not a right triangle.(A right angle's lines are perpendicular. Those are what make it a 90 degree angle.)
a right angle triangle.
parallelogram
rectangle
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 shape with no right angles and one pair of parallel lines would be called a trapezoid in the USA, and a trapezium in Britain.
