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.
There are infinitely many 2d shapes so it is impossible to list them all.
here are some: 2d shapes- square circle triangle Rectangle 3d shapes- cone cuboid cube prism

a 2d shape can only ever contain 1 face!

Just about any shape that isn't a circle can have two or more acute angles. But with some of them, you need to make them have acute angles.
Impossible.
A 2D shape with four straight sides and no right angles is called a rhombus. In a rhombus, all four sides are of equal length, but the angles are oblique, meaning they are either acute or obtuse. Another example of such a shape is a trapezoid that does not have any right angles. Both shapes are classified as quadrilaterals.
Shapes can be classified based on the number of sides they have (e.g. triangle, quadrilateral), their angles (e.g. acute, obtuse), or their dimensions in 2D or 3D space (e.g. circle, sphere). They can also be categorized as regular or irregular based on the uniformity of their sides and angles.
A kite.
A cone has no acute angles because a cone is a 3D shape and not a 2D.
square
A 2D triangle is simply referred to as a "triangle." It is a geometric shape with three sides and three angles. Triangles can be classified based on their side lengths (such as equilateral, isosceles, and scalene) or their angle measures (such as acute, right, and obtuse).
No
A three-angled 2D shape is called a triangle. Triangles can be classified based on their angles as acute, right, or obtuse, or based on their sides as equilateral, isosceles, or scalene. Each triangle has three sides and three vertices.
