A rhombus (UK), or rhomboid (US), is a quadrilateral parallelogram which can have no right angles. An example is the plane shape we refer to as a 'diamond'. A right-angled rhombus is called a square.
If only two sides of the quadrilateral plane figure are parallel, it is called a trapezium (UK), or trapezoid (US). The two sides which are not parallel may or may not be of equal lengths. If their lengths are equal the shape is called an isoscoles trapezium;
Normally, a parallelogram does not have a right angle.
A right angle.
A rectangle.
Right angle and acute
a rectangle
Yes a parallelogram with a right angle is a square.
Normally, a parallelogram does not have a right angle.
A parallelogram with one right angle has four of them. The name for this figure is a rectangle.
A parallelogram, in general, has no right angles.
Yes a parallelogram with a right angle is a square.

A square is a type of parallelogram.
A right angle.
A rhombus is an equilateral parallelogram that does not have a right angle.
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.
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.
