A rhombus
With 2 acute and 2 obtuse angles it has 4 angles - the shape is a quadrilateral. The shape can be one of trapezium, parallelogram, rhombus, kite or a general quadrilateral. With the two acute angles next to each other (forcing the two obtuse angles to be next to each other) the shape can be either a trapezium or a general quadrilateral.
A quadrilateral is any shape with four sides; angles can be acute or obtuse. A perfect square is the only quadrilateral with only right angles.
A kite, a parallelogram, many ordinary quadrilaterals with no specific names.

If the shape has 3 angles in all, where two of the angles are acute, then the shape is a scalene triangle.

With no acute or obtuse angles, the shape must only have right angles. For a quadrilateral, that limits it to a square or rectangle. Because each side has a different length than the one next to it, it has to be a rectangle.(Or, it could be a shape with any amount of sides above 4, as long as the angles are all right angles)

With 4 angles it will be a quadrilateral. Depending upon which angles are acute and which are obtuse and their sizes, and the side lengths it could be:a general quadrilaterala parallelograma rhombusa trapeziuma kite
