A rectangle is a quadrilateral with opposite sides parallel and congruent and four right angles. If all four sides are congruent, it is a square.

A square has 4 equal sides, and 4 equal angles and are considered paralellagrams A rectangle has 4 equal angles but not necessarily 4 equal sides, it is also a parallelagram.. On a square all sides are congruent, while in a rectangle only opposite sides are. So when is a square not a rectangle? what defines a rectangle and a square, each shape has to have 4 right angles. the sides are parallel and that in a square all four sides are congruent while in a rectangle only the opposite sides are congruent. So a rectangle must have opposite sides that are parallel and equal and four right angles. A square must have opposite sides parallel, all sides congruent, and four right angles. a rectangle is a parallelogram with four right angles, while a square is a parallelogram with four congruent sides and four right angles. By this definition a rectangle is a square since it has opposite sides that are congruent and parallel and it has four right angles. The question is, why a rectangle is not a square? A rectangle is not a square because it is not required to have four congruent sides.

C. Both pairs of opposite sides are congruent and parallel.

A trapezoid Trapezoid - 2 congruent diagonals that do not bisect each other. No right angles and has 1 pair of opposite parallel sides.

If one angle is right, then all angles are right. The diagonals of a parallelogram bisect each other. Opposite angles are congruent. Opposite sides are congruent. Consecutive angles are supplementary.
