Shapes let you do so much in PowerPoint. Once you master the art of adding and working with shapes, you can do so much. For example, you can place circles of various sizes one on top of the other to create something that looks like a target. Similarly, you can create seemingly complicated arrangements of shapes quite easily to create something that illustrates a concept or idea so much better than mere bulleted text. To create any such graphic content, you need to start by inserting common shapes. PowerPoint Online, the browser-based version of PowerPoint makes it easy to do so.
