a rectangle has 4 right angles
An acute angle is less than 90 degrees. Therefore, as a rectangle has 4 right-angles (90 degrees) there are no acute angles.
Except for the special case of a rectangle, a parallelogram must have two acute angles.
The difference is: 1) the rectangle has all right angles 2)a parallelogram has acute and obtuse angles but not a rectangle
