The order is 2.
<h3>Further explanation</h3>
- A rhombus has all sides equal length, or in other words, a rhombus is a quadrilateral with four similar sides.
- The opposite sides are parallel.
- Diagonals bisect in 90°.
- The opposite pair of angles are the same, e.g., ∠A = ∠C and ∠B = ∠D on the ABCD rhombus.
- A rhombus has two lines of symmetry. They are perpendicular to each other. The symmetry lines can also be said as the line of reflection symmetry.
- The order of rotational symmetry for a rhombus is two.
Let's distinguish the rhombus with a kite.
- Each rhombus is a kite.
- Every quadrilateral that is both a kite and parallelogram is a rhombus.
The formula for the rhombic and kite area is as follows:

- d₁ = diagonal-1
- d₂ = diagonal-2
