It doesn't matter, a parrallelogram doesn't have any right angles.

but, not all of parallelograms can have right angels seen here:|dw:1357748269189:dw|
Yes, but a parallelogram's opposite sides also add up to sides add up too 180 degrees, but not all the sides are equal. Thus, if the sides are not all equal in length they cannont all be 90 degrees.
