The "base" refers to any side of the triangle where the height is represented by the length of the line segment drawn from the vertex opposite the base, to a point on the base that forms a perpendicular. Given the length of two sides and the angle between them, the following formula can be used to determine the area of the triangle.

Properties. 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 )
