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 kite.
A cone has no acute angles because a cone is a 3D shape and not a 2D.
square
No
Squares
Polygon
It is a 2D shape that has 4 sides It belongs to the class of polygons known as quadrilaterals It has 4 equal sides It has 2 equal obtuse angles and 2 equal acute angles It has 2 diagonals that bisect each other at 90 degrees Its 4 interior angles that add up to 360 degrees
Squares
They are both 2D shapes and have exterior angles that add up to 360 degrees
2d shapes are shapes that can only be seen from the front unlike 3d shapes and they are flat
