Rhombus: A rhombus is essentially a type of paralleloram (opposite sides being parallel and equal). All the four sides in rhombus are congruent.
The diagonals of rhombus bisect the angle at the vertex into two equal halves.
The two diagonals are also perpendicular to each other.
The area of rhombus can be calculated using the formula, A = 1/2 x [Diagonal 1 x Diagonal 2]
Square: Square has the properties of rectangle as well as rhombus.
The sides of the square intersect each other at 90-degrees i.e. the angles are the corners are 90 degrees each.
All the four sides are congruent.
