The Polygonal Lasso is a selection tool commonly used in graphic design and photo editing software, such as Adobe Photoshop. It allows users to create a selection by clicking multiple points around an object, forming a polygonal shape. This method is particularly useful for selecting irregularly shaped areas that are difficult to capture with standard selection tools. Once the selection is made, users can manipulate the chosen area, such as cutting, copying, or applying effects. The Polygonal Lasso is favored for its precision, enabling detailed editing while maintaining control over the selection process.
