Theory & Formula
A trapezoid (or trapezium) is a quadrilateral with exactly one pair of parallel sides. The parallel sides are called bases, and the perpendicular distance between them is the height.
Key properties:
- Area: A = ½ × (base₁ + base₂) × height
- Perimeter: P = base₁ + base₂ + side₁ + side₂
- One pair of parallel sides (bases)
- Height is perpendicular to both bases
- Isosceles trapezoid has equal non-parallel sides
\(A = \frac{1}{2} \times (a + b) \times h\)
