Formulas
- Area: A = ½ × (a + b) × h
- Median (midsegment): m = (a + b) / 2
- Perimeter: P = a + b + c + d
An isosceles trapezoid has equal legs (c = d). A right trapezoid has one leg perpendicular to the bases (equal to h).
Trapezoid calculator
A trapezoid has two parallel sides (bases a and b) and a perpendicular height (h) between them. Enter the bases and height; optionally enter the two legs to get the perimeter.
