Two different types of shapes would be a circle and a square. they differ from each other in the fact that a circle's shape is perpetual as a square has four equal sides and four corners.
At least one of the sides must be curved for a two sided shape. If the curved shape is part of a circle you will have shapes like a segment of a circle, a crescent or a convex lens. The types of shapes can be increased greatly if the curved side can be elliptic, or even better, just a wobbly line.
