Rectangle
Rectangle
A 2D shape bounded by four line segments forming four 90-degree internal angles.
Properties
  1. It is 2D counterpart of a cuboid.
  2. Vertex: A corner of the rectangle. A rectangle has 4 vertices.
  3. Diagonal: A line segment joining two opposite vertices of the rectangle.
  4. A rectangle has 4 sides and 4 vertices.
  5. It has 2 equal diagonals which are bisectors of each other.
  6. Opposite sides of a rectangle are equal and parallel, i.e. it is a parallelogram.
  7. It can be defined as an equiangular quadrilateral.
Area of Rectangle (A)
A = l × w
l: length, w: width
Perimeter of Rectangle (P)
P = 2(l + w)
l: length, w: width
Diagonal of Rectangle (d)
d = l2 + w2
l: length, w: width
