A parallelogram is a four sided polygon with opposing parallel sides of equal length. Then if it has four right angles, the polygon becomes a rectangle.
parallelogram
A parallelogram with one right angle has four of them. The name for this figure is a rectangle.
Rectangle
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, 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.
Yes. If it has ONE right angle, then ALL four angles are right angles.
A rhombus, or, if there is a right angle, a square.
No because it could be a right angled trapezoid. A rectangle must have 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. The right angled trapezoids that are not rectangles are not parallelograms.
Yes a parallelogram with a right angle is a square.
A rectangle. Since it has two pairs of lines of identical length, then there is no way to have one right angle without all four being right angles (unless you change the lengths and then it is not a parallelogram). If you have four right angles, then you have a rectangle.
It's a rectangle. (And that includes the possibility of a square).The answer would be the same if you only said "... a parallelogram with a right angle."
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).
