Well, a trapezoid doesn't always have to be a mirror image of the "traditional" ones you often see in math books. They can often look weird and misshapen. But, when it comes to their legs, that's a whole other subject. A trapezoid must have exactly one pair of parallels sides. Their lengths do not have to be equal, or congruent, just as long as they are aligned.
If the trapezoid is an isosceles trapezoid, with congruent legs, then the base angles are congruent. Otherwise, no.
