A rhombus and a parallelogram but not a rectangle or a square
a rombus
A rhombus has two pairs of equal angles, the pairs being supplementary. Normally one pair is acute and the other is obtuse. In the special case, all four are right angles and the rhombus becomes a square.
It has 2 pairs of opposite equal angles which are acute and obtuse.
If two of the angles of a parallelogram are acute, then the other two angles will be obtuse. Since a parallelogram contains two pairs of parallel sides, both of the acute angles and both of the obtuse angles respectively will measure the same.
It is a parallelogram.
1.) Acute Angle 2.) Obtuse Angle 3.) Right Angle

a 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.
