A parallelogram.

Not sure about "parellel" but a quadrangle with two pairs of parallel lines MUST be a parallelogram.
A diamond has two pairs of parallel lines.
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.
It has two pairs of parallel lines so yeah
If the two lines are parallel, then you get 4 pairs of vertical angles. If the two lines are not parallel, then we get 6 pairs of vertical angles.
