not all parallerogram have right angle only square and rectangle have 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).
there are 4 angles and normally, there would be 2 angles that are smaller than a right angle Except of cause if the parallelogram is a square or a rectangle, all angles are equal to 90 i.e. right angle
A rectangle. Any quadrilaterial with two pairs of parallel sides is a parallelogram. And each side will be the same dimension as its opposite. It must be if there are two pairs of parallel sides. And if one interior angle is right, then all the interior angles are right angles. You may have a square, but it is only a special case of a rectangle, which you must have if your figure is constructed with the given constraints.
There are no acute angles in a rectangle which has 4 equal interior right angles
Yes. If it has ONE right angle, then ALL four angles are right angles.
A 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.
a rectangle
Because it has 4 interior right angles whereas a parallelogram has 2 obtuse angle and 2 acute angles.
A parallelogram with one right angle has four of them. The name for this figure is a rectangle.
Because it has 4 interior right angles whereas a parallelogram has 2 obtuse angle and 2 acute angles.
Rectangle
A parallelogram with a right angle is a rectangle.
A rectangle is a parallellogram with one right angle; A parallelogram is a quadrilateral with opposite sides equal and parallel.
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.
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.
