Normally, a parallelogram does not have a right angle.
No parallelogram can have only one right angle. The consecutive angles of a parallelogram must be supplementary, meaning they must add up to 180. 180-90=90, so all the angles must be right angles.
One pair of opposite angle is greater than a right angle.
A parallelogram with one right angle has four of them. The name for this figure is a rectangle.
No.
No.
Yes a parallelogram with a right angle is a square.

No, a parallelogram has no right angles.Additional answerIt might do. It could be a square or a rectangle. These are both forms of parallelogram. But it cannot have just one right angle. It either has four or none.
Definition I was taught: "A rectangle is a parallelogram with one right angle" Sounds weird but when you think it out, having one right angle in a parallelogram means the other three must be right as well.
No because it could be an irregular quadrilateral that includes a right angle. A rectangle has four right angles.Yes, a parallelogram with a right angle is always a rectangle. In fact, in my geometry book, some 55 years ago, such was the definition of rectangle.A parallelogram with one right angle will always have four right angles.It is true that you can draw an irregular quadrilateral with a right angle which is not a rectangle but the figure will not be a parallelogram.
no only 2acute angle n 2 obtuse angle A right angle would make it a rectangle - still a parallelogram but a special one with a specific name.
If you mean if one of the angles is a right angle, then yes, because a rectangle is the only option left if it is to remain a parallelogram.
A parallelogram cannot have just one right angle. If it has one, all four of its angles must be right angles and so it must be a rectangle (or, as a special case, a square).
Yes. If it has ONE right angle, then ALL four angles are right angles.
