Frequently Asked Questions
What makes a trapezoid irregular?
An irregular trapezoid has legs of different, unequal lengths and non-matching leg angles, unlike an isosceles trapezoid where the legs mirror each other, or a right trapezoid where one leg is perpendicular to the bases.
Does the area formula change for an irregular trapezoid?
No, the core area formula, average of the bases times height, is identical for every trapezoid regardless of leg shape, since it only depends on the two parallel bases and the perpendicular distance between them.
Can I find the legs and angles of an irregular trapezoid too?
Yes, if you know the bases, height, and how far each base extends past the other horizontally, the legs can be found with the Pythagorean theorem, and the angles from basic trigonometry, though this calculator focuses on area only.
