Is a rhombus and a diamond the same?
Emily Ross
Published Jan 07, 2026
Diamond, Rhombus, and Trapezoid are all quadrilaterals, which are polygons with four sides. While rhombus and trapezium are properly defined in mathematics, diamond (or diamond shape) is a layman's term for rhombus. A quadrilateral with all sides equal are in length is known as a rhombus.
Why is a diamond not a rhombus?
I pointed to the kite and asked about that one, since it has four sides. “Could we call this a rhombus?” They said no because the sides weren't equal, so not a rhombus. And because it didn't have five sides, not a diamond either.
Why do we call a rhombus a diamond?
The rhombus is often called a 'diamond', after the diamonds suit in playing cards which resembles the projection of an octahedral diamond, or a lozenge (shape), though the former sometimes refers specifically to a rhombus with a 60° angle (which some authors call a calisson after the French sweet – also see Polyiamond) ...

Is a square a diamond?
A simpler explanation would be all angles inside a square are equal to 90°. If you have a shape that has 4 equal sides, but only opposite angles are equal, it's a diamond.
Is a diamond a rock?
The actual reason why a diamond is not considered a rock is because of its composition. A rock, by definition, is a substance that is made up of two or more minerals. Rocks are what we commonly see in nature and while they are made up of minerals, they are not specific.

Are all sides of a diamond equal?
Diamonds are unique shapes because they have many different geometric attributes. A diamond is a quadrilateral, a 2-dimensional flat figure that has four closed, straight sides. But a diamond is also categorized as rhombus, because it has four equal sides and its opposite angles are equal.
Is a diamond a parallelogram yes or no?
The opposite sides are parallel, but the corners do not form right angles. A diamond shape is a good example of a rhombus. A rhomboid has four parallel sides. The opposite sides are equal, but the corners do not form right angles.

Is every rhombus a square?
Therefore, the square is always a rhombus but a rhombus may not necessarily be a square. A square is always a rhombus since all the sides of a square are equal in length. In addition to this, the diagonals of both the closed figures, square and rhombus are perpendicular to each other and bisect the opposite angles.
What is difference between rhombus and rectangle?
A rhombus has four equal sides, whereas, in a rectangle, the opposite sides are equal. The diagonals of a rhombus bisect each other at 90°, whereas the diagonals of a rectangle bisect each other at different angles. In a rhombus, the opposite angles are equal, whereas, in a rectangle, all angles measure 90°.
