a rectangle
A rectangle has four sides whereas a right angle triangle has only three sides.
a rectangle
Each angle of a rectangle is a right angle. (90°)
From its right angle. right angle --> rect angle.
A rectangle has four right angles (i.e. each corner).
A rectangle has 4 interior right angles at each corner
No, because a rectangle has 4 right angles.
A parallelogram with one right angle has four of them. The name for this figure is 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.
Yes, that is what is rectangle is. One can prove that all of the angles are right angles.
They have atleast one 90 degree angle.
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.
Yes. If it has ONE right angle, then ALL four angles are right angles.
FALSE because a rectangle has 4 right angles.
A right angle - whether or not in a rectangle - is 90 degrees.
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.
