The shape that has 2 acute angles and 2 obtuse angles is a trapezoid (specifically, an irregular trapezoid). In geometry, a trapezoid is defined as a four-sided figure (a quadrilateral) that has at least one pair of parallel sides. In an irregular trapezoid, the angles can vary widely, and it is possible for it to have two acute angles (angles less than 90 degrees) and two obtuse angles (angles greater than 90 degrees but less than 180 degrees).
For example, if you visualize a trapezoid where one pair of angles is sharp (acute) and the other pair is more stretched out (obtuse), you can easily picture how such a shape would fit the criteria. This property can also be seen in some other irregular quadrilaterals, but the trapezoid is a common example that fits your description perfectly.
