Does A Quadrilateral With Three Congruent Sides Have To Be A Trapezoid?

A quadrilateral with three congruent sides can be a trapezoid with one horizontal side and both diagonals congruent where there would be a vertical line of symmetry. Does a quadrilateral with three congruent sides have to be a trapezoid?

A trapezoid is formed if the two angles between each pair of adjacent congruent sides are congruent.

What if those same two angles are not congruent?
Thanks from topsquark

I guess it doesn't have been a trapezoid. I attached a quadrilateral I drew attempting to make the three sides other than the bottom be congruent.
