Parallel lines have equal slopes. If the two of the opposite sides of your quadrilateral have equal slopes, you, at least, have a trapezoid. If the other two sides also have equal slopes, you have a parallelogram. If none of the pairs of slopes are equal, then you just have a general quadrilateral.
