There are 4 right angles in a parallelogram.
No, it has two angles over 90 degrees and two angles below 90 degrees.
Not possible... in order for it to have four right-angles, it would resemble a square or rectangle.
Almost but not quite because a rectangle has 4 equal right angles whereas a parallelogram has 2 equal opposite obtuse angles and 2 equal opposite acute angles.
as a paralellogram is a skewed square, it is a quadrilateral. it has four sides
