Any shape with 4 acute angles must have more than 4 sides. Any shape with more than 4 sides can have 4 acute angles (but doesn't have to).
I'm not sure but i think it might be 4 acute angles but i suggest you try a more accurate site.
parallelogram
Can't happen. The 4 interior angles of any 4-sided figure add up to 360 degrees. This alleged thing supposedly has 4 acute angles, meaning 4 angles of less than 90 degrees each. 4 times (less than 90) = (less than 360). No such shape.
