Trapezoid Perimeter Area Angle Calculator

To use this calculator you need to know the 4 sides of the trapezoid

Lines BC and AD are parallel and are called the base

Lines AB and DC are called the side

Lines AC and DB are called the diagonals

The line perpendicular to AD & BC is called the height of the trapezoid.

The line parallel to AD & BC and located between AB and DC is called the median line

Median line = (AD + BC) ÷ 2
