About this calculator
A rhombus has four equal-length sides and diagonals that meet at right angles. The diagonal formula (d₁ × d₂ / 2) is convenient because diagonals are easy to measure with a tape across the corners. Equivalent: A = side² × sin(angle).
Frequently asked
Yes — that's a defining property. They also bisect each other (cross at their midpoints).
