Rhombus and square are two common geometric shapes that often cause confusion due to their similarities. In this article, we will delve into the relationship between a rhombus and a square, comparing their properties, similarities, and differences. Understanding these shapes’ characteristics can help clarify their relationship and enhance your grasp of geometric concepts.
Understanding a Rhombus
A rhombus is a quadrilateral with all four sides of equal length. The opposite sides of a rhombus are parallel, and its opposite angles are equal. Additionally, the diagonals of a rhombus bisect each other at right angles. In simple terms, a rhombus is a parallelogram with adjacent sides of equal length.
Properties of a Rhombus:
 All sides are equal in length.
 Opposite angles are equal.
 Diagonals bisect each other at right angles.
 Diagonals are perpendicular bisectors of each other.
 Diagonals are of different lengths.
Exploring a Square
A square is a specific type of rhombus with additional characteristics. A square is a quadrilateral with all four sides of equal length and all angles measuring 90 degrees. In essence, a square is a rhombus with right angles.
Properties of a Square:
 All sides are equal in length.
 All angles measure 90 degrees.
 Opposite sides are parallel.
 Diagonals are equal in length and bisect each other at right angles.
 Diagonals are perpendicular bisectors of each other.
Relationship Between a Rhombus and a Square
Now that we have explored the individual properties of a rhombus and a square, let’s delve into their relationship and how they are interconnected.
Similarities:
 Equal Side Lengths: Both shapes have all sides of equal length, making them equilateral quadrilaterals.
 Diagonals’ Relationship: The diagonals of both shapes bisect each other at right angles and are perpendicular bisectors.
Differences:

Angle Measurements: The main difference between a rhombus and a square lies in their angle measurements. While a rhombus does not have all angles measuring 90 degrees, a square has all interior angles measuring 90 degrees.

Additional Shape Constraint: A square is a more specific form of a rhombus that has the added constraint of right angles.
Notable Distinctions

Rhombus as a General Form: A rhombus is a more general term that encompasses all foursided figures with equal length sides. It is a broader category compared to a square.

Square as a Special Case: A square, on the other hand, is a specific type of rhombus that has the additional feature of all angles measuring 90 degrees. It is a more restrictive form of a rhombus.

Symmetry: Both shapes exhibit symmetry but in different ways. A rhombus exhibits twofold symmetry about each of its diagonals, while a square exhibits fourfold symmetry about its center.
Constructing a Square from a Rhombus
One interesting aspect of the relationship between a rhombus and a square is the process of transforming a rhombus into a square. Since a square is a special case of a rhombus with right angles, we can construct a square from a rhombus by adjusting its angles.
Steps to Construct a Square from a Rhombus:
 Start with a rhombus with all sides of equal length.
 Identify one of the angles of the rhombus.
 Rotate one of the points of the rhombus by 45 degrees to create a right angle.
 Adjust the other angles accordingly to ensure all interior angles measure 90 degrees.
 Once all angles are right angles, the rhombus has transformed into a square.
This construction highlights the direct relationship between a rhombus and a square, showcasing how a square is a specialized version of a rhombus with additional properties.
