A rectangle.
A figure with four sides, two of which are parallel and with no right angles, is called a trapezoid (or trapezium in some countries). In this shape, the parallel sides are known as the bases, while the other two sides are called the legs. The angles between the legs and the bases can vary, which is why there are no right angles in this configuration.
Depending on the definition that is used, a trapezium is either a figure with four sides that has no parallel sides (American) or a figure with fours sides that has two parallel sides (British). Either way, a trapezium can not have 3 right angles.

A trapezoid is a quadrilateral which has two parallel sides.

A four-sided figure with two pairs of parallel sides the same length and four right angles is called a square.

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.
