bc if you look at the other choices they arent true.. if yalls dont know what a trapezoid looks like, i think you should go back to elementary :) I still dont know my lefts and rights
D one pair of opposite sides is parallel is the answer because trapezoids are another pair angled towards each and if you follow long enough they will intersect. A couldn't be true because if ALL the angles are corresponding angles you would need two pairs of parallel lines. B isn't correct because the sides would need to be parallel for that too. C well you've already proved they don't have two pairs of parallel lines.
