The Lasso (L) is a flexible tool, somewhat resembling the selection equivalent of the Pen tool. We can also use the Lasso tool to split shapes or select portions of a line or a shape.
           It has three options in the Tools panel: the Polygon mode button, the Magic Wand, and the Magic Wand properties.

            The Polygon mode option is used to select an object or an area by creating linear and interconnected lines.

            The Magic Wand option of the Lasso tool is used to select ranges of a similar color in a bitmap that has been broken apart. After select areas of the bitmap, we can change their fill color or delete them.
