Descrição: dc.descriptionThis geometric Demonstration establishes that the area of a parallelogram bounded by vectors (a,c) and (b,d) is /ad-bc/ Use the sliders to see how various parallelograms can be transformed into ones of equal area with their bases on the x axis. If the x axis does not intersect the parallelogram, slide the triangular portion farthest from the x axis toward it. If the axis does intersect the parallelogram, slide the triangular portion cut off by the x axis to the farther end of the parallelogram. In the examples shown, the height of the resulting parallelogram is /d/and its base is determined by the x axis intersection of the line joining (a,c) to (a+b,c+d), which is easily seen to be (ad-bc)/d. Thus the area is /ad-bc/ Clearly the same result holds if, due to the choice of triangular portion, the roles of (a,c) and (b,d) are interchanged-
