How does the Parallelogram Calculator work?

Area = base × height (height perpendicular to base) Then: Perimeter = 2 × (side 1 + side 2) Then: Diagonals: d₁² + d₂² = 2(a² + b²) (parallelogram law) Then: Angles: opposite equal, adjacent supplementary (sum to 180°).

Can you give an example of how to use the Parallelogram Calculator?

Example: Input base=6, height=4 gives a result of Area 24.
