how do you decide if the angles in a parallelopiped are 90 degrees?

Directrix (directrix):

If the parallelepiped is a rectangular solid, then it has right angles. The questions seems vague. Is there more to the question other than what you posted? @NyikoPearl

OpenStudy (anonymous):

If all the angles are 90, then it will be a box.

Okay, take every point and subtract point A from it.

That will give you 3 vectors for the parallelopiped.
