Calculates rhombus area, perimeter, and diagonal lengths. Specializes parallelogram with equal sides.
Formule
Area = (d₁ × d₂) / 2 where d₁, d₂ = diagonals
Guide étape par étape
- 1Area = (d₁ × d₂) / 2 where d₁, d₂ = diagonals
- 2Perimeter = 4 × side
- 3Diagonals bisect at 90° and each other
- 4Side = √((d₁/2)² + (d₂/2)²)

- ✕Confusing diagonal with side in calculations
Questions fréquentes
What's the difference between rhombus and square?
Rhombus: equal sides, no angle requirement; square: equal sides AND all angles 90°.
Why is diagonal formula d₁ × d₂ / 2?
Diagonals divide rhombus into 4 right triangles; area = sum of triangles.
