Pronunciation: [ɹˈɒmbəs] (IPA) 
The word "rhombus" is spelled with an "h" in the middle, although it may not be pronounced that way by everyone. The IPA phonetic transcription for "rhombus" is rɑmbəs. The "r" sound in the beginning is followed by a short "o" sound, then a "m" and a "b" pronounced together, ending in a short "u" sound. The silent "h" in the middle is sometimes added by speakers to make it clearer that the "b" is pronounced separately from the "m."
A rhombus is a geometric shape that falls under the category of quadrilaterals. It is a four-sided figure in which all four sides are equal in length. Each interior angle of a rhombus measures 90 degrees, making it a parallelogram with perpendicular diagonals. The opposite sides of a rhombus are parallel to each other, while the opposite angles are congruent.
The distinctive feature of a rhombus is that all of its sides are of equal length, providing it with a unique symmetry. Its diagonals bisect each other at right angles, creating four congruent right triangles within the shape. The diagonals of a rhombus also divide it into four congruent interior angles. Furthermore, a rhombus possesses reflective symmetry, meaning it can be folded along its diagonals to yield overlapping congruent halves.
The area of a rhombus can be calculated by multiplying the lengths of its diagonals and dividing the result by two. The perimeter of a rhombus is obtained by multiplying the length of one of its sides by four.
Rhombuses are commonly encountered in various fields of study, including mathematics, engineering, and art. They are often utilized in the design of tiles, emblems, and logos due to their visually appealing and balanced structure. Within mathematics, rhombuses serve as fundamental objects for studying properties related to parallelograms, quadrilaterals, and symmetry.
A four-sided figure whose sides are equal, but whose angles are not right angles.

The word "rhombus" comes from the Greek word "rhombos", which means "spinning top" or "whirling motion". It is derived from the verb "rhein", which means "to flow" or "to move quickly". The term was originally used in geometry to describe a quadrilateral with opposite sides parallel and equal in length, but it has since been more specifically defined as a parallelogram with all sides congruent.
