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.
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
yes
A rhombus has 2 opposite acute angles and 2 opposite obtuse angles
2 obtuse and 2 acute in the classic kite shape.
A parallelogram
An obtuse triangle or an isosceles triangle if the 2 acute angles are equal in size
It is just an irregular quadrilateral.
Any parallelogram except a rectangle.
