The Shapes gallery in PowerPoint consists of various shapes, both open and closed. Closed shapes are ones that do not have a “visible” beginning or an end such as the Rectangle, Ellipse, and Triangle shapes. Open shapes have a “visible” beginning and an end. An example of an open shape is a straight point to point line. Some tools within the Shapes gallery let you create both open and closed shapes; these are the Freeform Line, Curve, and Scribble tools. In addition, you can convert any closed shape into an open shape and vice versa, as you will learn in this tutorial.
