A abh 2 A a b h 2 Here a a and b b are the lengths of the parallel sides of the trapezoid and h h is the height or the altitude or the distance between the two parallel sides of the trapezoid. Property 1 The angles on the same side of a leg are called adjacent angles and are supplementary more Property 2 Area of a Trapezoid A r e a h e i g h t sum bases 2 more Property 3 Trapezoids have a midsegment which connects the mipoints of the legs more. Steps Start by observing that if we duplicate the trapezoid and rotate it so that two of the same angle ends are touching we get the shape of a parallelogram.
