Because a rectangle has 4 corners that meet each other at 90 degrees and so therefore a rectangle has 4 interior right angles that add up to 360 degrees
Each angle of a rectangle is a right angle. (90°)
From its right angle. right angle --> rect angle.
A right angle - whether or not in a rectangle - is 90 degrees.
A rectangle

a rectangle
Yes it is.
A rectangle.
its a right angle
A rectangle has four sides whereas a right angle triangle has only three sides.
By definitions: two levels of them. If it is has a right angle, it must be 90 degrees. If it is a rectangle it must have right angles, otherwise it is not 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.
