# Rhomboid vs. Parallelogram: What's the Difference?

Edited by Sawaira Riaz || By Sumera Saeed || Updated on November 3, 2023

A rhomboid is a quadrilateral with opposite sides parallel and adjacent sides unequal, while a parallelogram has opposite sides parallel and equal.

## Key Differences

A rhomboid is a type of quadrilateral whose opposite sides are parallel to each other but adjacent sides are of unequal lengths and angles between sides are not 90 degrees. In a rhomboid, opposite angles are equal, and adjacent angles are supplementary.

A parallelogram is a more general geometric term for a four-sided figure with two pairs of parallel sides. In a parallelogram, opposite sides are not only parallel but are also equal in length, and opposite angles are equal. This makes every rhomboid a parallelogram, but not all parallelograms are rhomboids.

The term rhomboid often refers to a slanted parallelogram, one that does not contain right angles, unlike rectangles which are also a type of parallelogram. Rhomboids can resemble a stretched diamond shape, which is actually called a rhombus - a special kind of parallelogram with all sides equal.

Parallelograms include a variety of shapes including rectangles, rhombuses, and rhomboids. The defining feature is their parallel opposing sides. The internal angles of a parallelogram adjust to maintain the parallel structure, which means the angles can be obtuse or acute, but always in pairs.

While both rhomboids and parallelograms have sides opposite to each other that are parallel, the lengths and angles can differ. Rhomboids focus on the parallel aspect without the requirement of equal-length sides, whereas parallelograms have the additional characteristic of equal-length opposite sides.
