There are no right angles in a parallelogram. A parallelogram only has right angles if it is a rectangle, in which case it has exactly four.
Parallelogram have 4 right angles. (because, square and rectangle is also parallelogram)
Usually zero. If your parallelogram happens to be a rectangle, 4.
If the parallelogram is a square or a rectangle, then there are four right angles, otherwise there are none.
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.
None normally but in the form of a rectangle it will have 4 right angles
Four; it's like a rectangle but without right angles.
All the angles of a rectangle are right angle. This is not necessarily true of a parallelogram. There are many other differences that arise from this difference.
A parallelogram doesn't need any right angles in order to be a parallelogram.If it has any, then it's a special kind of parallelogram, called a "rectangle".Note:The way the properties of a parallelogram work out,if it has one right angle, then it has four of them.
