No, a paralleogram that has even one right angle must have all right angles in order to keep the opposite sides parallel.
So, a parallelogram will have either no right angles (in which case it will always have 2 acute angles and two obtuse angles) or it will have 4 right angles (in which case it will be called a square or a rectangle, and will obviously have no acute or obtuse angles).

How many acute angles are there in a parallelagram?
A parallelogram has 0 or 2 acute angles. If the parallelogram happens to have four right-angled corners, it is still a parallelogram (and a rectangle), but no acute angles.
What characteristics help classify a quadrilateral as a parallelogram and not a rectangle?
a rectangle has 4 right angles, a parallelogram has 2 acute angles and 2 obtuse angles
What is the difference between rectangle and parallelogram?
The difference is: 1) the rectangle has all right angles 2)a parallelogram has acute and obtuse angles but not a rectangle
What geometric shape has 2 acute angles and obtuse angles?
a trapezoid :) * * * * * Not necessarily. A trapezoid can have two right angles, one acute and one obtuse angle. A parallelogram which is not a rectangle must have 2 acute and 2 obtuse angles.
What property makes a rectangle a special type of parallelogram?
Because it has 4 interior right angles whereas a parallelogram has 2 obtuse angle and 2 acute angles.
