Diagonals are congruent.

Diagonalsbisect each other.

Each diagonalis perpendicu-lar bisector of the other.

A quadrilateral with each angle a right angle and opposite side congruent is called a .

• Every angle is right angle.• Opposite sides are congruent.• Opposites sides are parallel.• Diagonals are congruent .• Diagonals bisect each other.

A quadrilateral which has opposite

sides parallel is called a

parallelogram.

Diagonals bisect each

other

Opposite sides are parallel

Opposite angles are congruent

Opposite sides are

congruent

Only one pair of opposite side is
