The ones that have are called 'squares'.
No, not all rectangles have four congruent sides. While all squares are rectangles (since they meet the definition of having four right angles and opposite sides that are equal), rectangles in general can have sides of different lengths. Therefore, rectangles can have two pairs of equal sides but do not necessarily have four congruent sides like squares do.
A quadrilateral with congruent pairs of adjacent sides and no parallel sides is a kite.
Trapezoid.
They're sides may not be congruent.
Two pairs of adjacent sides are congruent. The angles between the non-congruent sides are congruent.
When two adjacent sides are equal (congruent).
adjacent sides of a rectangle are congruent
Rectangles have congruent adjacent angles.
No, rectangles do not have congruent sides. Squares have congruent sides.
yes rectangles do have adjacent sides that are perpindicular..... hope that helps....
No, only those rectangles that are squares have four congruent sides.
A quadrilateral with congruent pairs of adjacent sides and no parallel sides is a kite.
An impossibility. By definition a quadrilateral with 4 congruent sides must have congruent adjacent angles.
No because opposite sides of a rectangle are congruent and parallel

Trapezoid.
if the sides of two rectangles are equal then they r congrunt
