Using the idea of translations, you can tile the plane with strips of parallelograms arranged so that the top of the parallelogram exactly matches the bottom of a parallelogram in the next strip. You can also offset the strips so that the top of a parallelogram matches the midpoint of the top of a parallelogram in the next strip.
Find two ways that a copies of a parallelogram can be used to tile a surface.
