Diamond vs. Trapezoid: What's the Difference?
Edited by Aimie Carlson || By Harlon Moss || Published on February 24, 2024
A diamond is a quadrilateral with all sides equal and angles not necessarily right angles, while a trapezoid is a quadrilateral with only one pair of parallel sides.
Key Differences
A diamond, often confused with a rhombus, is a quadrilateral where all sides are of equal length but the angles can vary. In contrast, a trapezoid is defined by having only one pair of parallel sides, with the other two sides not being parallel.
The diamond shape is symmetrical, and its diagonals bisect each other at right angles, a feature not necessarily present in trapezoids. Trapezoids can have asymmetrical shapes, with their non-parallel sides being of different lengths.
In diamonds, opposite angles are equal, a property not shared by trapezoids, where only the angles on the parallel sides can be equal. The trapezoid is unique in that its parallel sides can be of different lengths.
The area of a diamond can be calculated using the product of its diagonals divided by two, whereas the area of a trapezoid is computed by averaging the lengths of the parallel sides and then multiplying by the height.
A diamond is a special type of parallelogram where all sides are equal, while a trapezoid does not necessarily fit into this category, as it only requires one pair of sides to be parallel.
