Identify the Quadrilateral

For each set of points determine if the quadrilateral formed by the points is a parallelogram or trapezoid. Plot the points Draw the quadrilateral Identify the quadrilateral by computing the slopes of the sides.

Plot A( 1, 0); B( 0, 4); C( 6, 7); D( 7, 3)

Identify the quadrilateral. Justify your answer with slopes of the sides.
