A rhombus (pushed over square) will give you 2 pairs of parallel, congruent sides, 2 acute angles and 2 obtuse angles.
parallelogram
A polygon with two acute angles, two obtuse angles, and two pairs of parallel sides is known as a trapezoid (or trapezium in some regions). Specifically, it can be classified as an irregular trapezoid, where one pair of opposite sides is parallel, and the angles vary in measure. This configuration allows for the presence of both acute and obtuse angles while maintaining the parallel sides characteristic of trapezoids.

A triangle having all angles less than 90 degrees is a polygon having no parallel sides and all acute angles.

A parallelogram is a quadrilateral with opposite sides parallel and congruent.
It could be a hexagon which is stretched out so that one pair of opposite angles become acute - but they must be different otherwise you will have three pairs of parallel sides.
