4 pairs
It has 2 pairs.
The rectangle has four corners.Every corner is a right angle.Every right angle is a place where two perpendicular lines meet.Looks like the rectangle has four pairs of perpendicular sides.
By definition, a parallelogram two separate pairs has parallel sides. The only type of parallelogram that has perpendicular sides is a rectangle. All others have non-perpendicular sides.
A rectangle is a 4 sided quadrilateral having 2 pairs of parallel sides and 4 interior right angles.
It could be a square or a rectangle

The rectangle.
A rectangle is a 4 sided quadrilateral having 2 pairs of parallel sides and 4 interior right angles.
A rectangle always has perpendicular sides.
Not necessarily; a rhombus has 2 pairs of opposite sides which are parallel, like the parallelogram, and its diagonals are perpendicular. (It also has all its sides of the same length.)
Yes a square has 2 pairs of perpendicular sides actually, 4!
Adjacent sides of a rectangle are perpendicular.
A square or a rectangle fits the given description
