The angles inside any shape with more than 7 sides always add up to more than 1,000 degrees.
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).
A shape that has more sides than a triangle or rectangle but fewer angles than a hexagon is a pentagon. A pentagon has five sides and five angles, which fits the criteria, as a triangle has three sides and angles, a rectangle has four sides and angles, and a hexagon has six sides and angles.
A shape that fits this description is a regular triangle, also known as an equilateral triangle. It has no right angles, all three sides are congruent, and the sum of its internal angles is 180 degrees, which is less than 360 degrees. Another example could be a regular polygon with more than three sides that are all congruent, such as a regular hexagon, but it will have right angles at some internal arrangements.
A straight line
Any shape that has more than 4 sides has all angles bigger than 90 degrees.
The angles inside any shape with more than 7 sides always add up to more than 1,000 degrees.
Squares and rectangles always have, but anyshapewith more than 3 sides can have 2 right angles.
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).
Any closed shape can have angles greater than 90 degrees. A triangle doesn't need to have any, but it can have one of them if it wants to. A shape with four sides doesn't need to have any, but it can have 2 or 3 of them if it wants to. Shapes with more than 4 sides must have some.

Another example could be a regular polygon with more than three sides that are all congruent, such as a regular hexagon, but it will have right angles at some internal arrangements.
A shape that can contain no acute angles is a rectangle. In a rectangle, all interior angles are right angles, which are exactly 90 degrees. This means there are no angles smaller than 90 degrees, which are considered acute angles. Therefore, a rectangle is an example of a shape that contains no acute angles.
It could be a parallelogram, but there are other shapes with more sides.
A straight line
There is no such shape because shapes or polygons must have 3 or more sides and there are 3 interior angles in a 3 sided polygon which is a triangle that add up to 180 degrees.
Assuming there are no more sides/angles, then it is a rectangle.
