All four of the angles of a rectangle (and of squares) are right angles.(Its name comes from this : rect-angle.)
A rectangle has 4 right angles
A rectangle has 4 right angles
A rectangle.
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.
A parallelogram with 4 equal right angles is a rectangle.
square
4 right angles, by definition, are four angles of the same measure, and therefore must be congruent angles.
A rectangle is also a polygon, a parallelogram, and a quadrilateral with four right angles.

It's a rectangle. A rectangle has four right angles, but only two pairs of equal sides.

No parallelogram can have only one right angle. The consecutive angles of a parallelogram must be supplementary, meaning they must add up to 180. 180-90=90, so all the angles must be right angles.
