    |dw:1336334568986:dw| With a pair of parallels.

    Adjacent side aren't equal. That' means|dw:1336334598892:dw| Figures A & B doesn't not meet requirements A is a square and B is a lozenge

    So our figure must be |dw:1336334701471:dw|

    Parallelogram is not possible, because it has 2 pairs of parallels.

    Now, we have A.) It is shaped as a trapezoid with adjacent angles which are congruent. and C.) It is shaped as a trapezoid with two pairs of supplementary adjacent angles. Let's draw A) |dw:1336334845861:dw| That would imply that this trapezoid is a rectangle, since adjacent angles are congruent, and a rectangle doesn't meet the requirements either.

    C.) It is shaped as a trapezoid with two pairs of supplementary adjacent angles. Two? So two of them must be 90 degrees, since supplementary angles = x+y=180 |dw:1336334972832:dw|

    It only has a pair of opposite side parallel; The adjacent sides of the figure are not congruent. Thus, statement C is true.
