The Polygonal Lasso Tool is part of the standard Lasso Tools. Select the Polygonal Lasso Tool from the list. Click on the Lasso Tool, then hold your mouse button down until a fly-out menu appears showing you the additional tools that are available.

We use a Lasso Tool to select an image in whatever shape we want. The Lasso Tools allow you to select precise areas of an image by drawing or tracing the selection outline. If you press and hold the Alt key while dragging then it will set the center of the rectangle to the point where your cursor had started. If you press and hold the Shift key while dragging your selection then it will always create a perfect square. This tool selects your image in a rectangular shape.
