A 2-dimensional four sided polygon is called as a Quadrilateral. Different types of Quadrilateral are
  • Opposite sides are parallel and equal.
  • Area = base x height
  • Two pairs of adjacent sides are equal.
    AB = BC and AD = CD
  • Diagonals intersect at right angles.
  • Area = (AC x BD)2
  • Opposite sides are parallel and equal.
  • Each angle in a rectangle is 90°.
  • Area = Length x width
  • All the four sides are equal.
  • Diagonals are perpendicular.
  • Area = (PQ × RS)2
A pair of sides is parallel.
Area = (a+b)h2
Here a, b are length of parallel sides
And h is the height.
  • All the sides are equal.
  • Diagonals bisect each other.
  • Each angle in a square is equal to 90°
  • Area = side²
