# Rhombus vs. Trapezoid: What's the Difference?

Edited by Sara Rehman || By Sumera Saeed || Published on February 8, 2024

**A rhombus is a parallelogram with all sides equal, while a trapezoid is a quadrilateral with only one pair of parallel sides.**

## Key Differences

A rhombus is a special type of parallelogram where all four sides are of equal length, creating a diamond-like shape. In contrast, a trapezoid, known as a trapezium outside North America, is defined by having only one pair of parallel sides, giving it a unique, uneven shape.

The angles in a rhombus can be varied but opposite angles are always equal, and adjacent angles are supplementary. In a trapezoid, the angles are not necessarily equal or supplementary, except in specific cases like the isosceles trapezoid.

Diagonals of a rhombus bisect each other at right angles and are of different lengths unless it's a square. The diagonals of a trapezoid do not necessarily bisect each other at right angles and can be of any length, depending on the trapezoid's shape.

In terms of symmetry, a rhombus has both line and rotational symmetry, making it a highly symmetric figure. A trapezoid typically has only one line of symmetry if it's isosceles but lacks rotational symmetry.
