What is the difference between a rhombus and a parallelogram?

Solution:

Parallelogram and Rhombus are four-sided polygons also known as quadrilaterals having four sides and four angles.

A parallelogram is a four-sided convex polygon with opposite sides parallel and equal with opposite angles being equal.

A rhombus is a special type of parallelogram where all the sides are equal in measure with opposite sides being parallel.

Let's tabulate the differences between a parallelogram and a rhombus as follows.

Parallelogram	Rhombus
In a parallelogram, opposite sides are equal in measure.	In a rhombus, all sides are equal in measure
Diagonals bisect each other.	Diagonals bisect each other at 90 degrees.
The perimeter of a parallelogram is equal to 2(a + b) where a and b are the side and the base respectively.	The perimeter of a rhombus is equal to 4x where x is the measure of each side of a rhombus.
The area of a parallelogram is given by b × h where b and h represent the base and the height respectively.	The area of a rhombus is given by d₁d₂/2 where d₁ and d₂ denote the length of the two diagonals.
Every parallelogram is not a rhombus.	Every rhombus is a parallelogram.
Below is the image shown for a parallelogram AB = CD, AD = CB	Below is the image shown for a rhombus AB = BC = CD = AD

Thus, a parallelogram has opposite sides equal, while in a rhombus all four sides are equal in measurement.

What is the difference between a rhombus and a parallelogram?

Summary:

The difference between a parallelogram and a rhombus is that a parallelogram has opposite sides equal, while in a rhombus all four sides are equal in measurement.
