Theory & Formula
A parallelogram is a quadrilateral with opposite sides parallel and equal in length. The area is calculated by multiplying the base by the perpendicular height.
Key properties:
- Area: A = base × height
- Perimeter: P = 2(base + side)
- Opposite sides are parallel and equal
- Opposite angles are equal
- Height is perpendicular to the base
\(A = b \times h\)
