If by four parallel lines you mean two pairs of parallel lines, then you would be looking for a parallelogram. An example of a parallelogram is at this address:

The arrowhead lines along the sides designate that the opposite sides are parallel and of the same length. The single and double lines in each section show that the portions of line in each segment are identically sized.
Draw a parallelagram this has the opposite sides parallel and no right angles
The figure, as described, is impossible. If a quadrangle has 2 pairs of parallel sides then the number of right angles can be 0 or 4, but not 2.
A rhombus for example
A right angle has no parallel lines, but it does have perpendicular lines that meet at right angles.
Such a quadrangle cannot exist. The right angle must be formed by one of the parallel sides and one of the non-parallel sides. Then the angle formed at the other end of that non-parallel side would also be a right angle (the non-parallel side would be a transversal intercepting the two parallels). But then the quadrangle has two right angles, and not just one. No its Trapezoid
Any quadrangle with two opposite angles which are 90 degrees.
Partly true.It is a quadrangle (or quadrilateral).It does have one pair of parallel sides.But it can have 0 or 2 right angles.

A trapesium.
