No but any four sided shape's interior angles total 360 degrees.
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).
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.
A straight line
Assuming there are no more sides/angles, then it is a rectangle.
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.
It could be a parallelogram, but there are other shapes with more sides.

A rectangle the same number of sides & angles. (4 sides & 4 right angles)
Because it is easier to use. If a right angle were to be 100 degrees when you compare it to 90, 90 has a lot more factors than 100. It's probably in the ancient days when people made it like that.
An irregular polygon with 5 or more sides.
