- - - - A rectangle is a quadrilateral.
      - The opposite sides are parallel and equal to each other.
      - Each interior angle is equal to 90 degrees.
      - The sum of all the interior angles is equal to 360 degrees.
      - The diagonals bisect each other.
      - Both the diagonals have the same length
  - - - The diagonals of a square bisect each other and meet at 90°.
      - The diagonals of a square bisect its angles.
      - Opposite sides of a square are both parallel and equal in length.
      - All four angles of a square are equal (each being 360°/4 = 90°, a right angle).
      - All four sides of a square are equal.
- - - - One pair of Parallel sides which should be opposite to each other.
      - One pair of non-parallel sides.
      - Sum of the angles of adjacent sides is 180°.
      - Diagonals of a trapezium bisect each other on intersection.
- - - - Two pairs of adjacent sides are equal.
      - One pair of opposite angles are equal.
      - The diagonals of a kite are perpendicular to each other.
      - The longer diagonal of the kite bisects the shorter diagonal.
      - The area of a kite is equal to half of the product of the length of its diagonals.
