Motion paths are essentially the paths (or lines) through which slide objects animate. These motion paths are just like any other line with curves, points, etc. If you are familiar with the drawing tools in PowerPoint (Line, Curve, Scribble, and Freeform), you know that paths can be either open or closed. A circle is a good example of a closed path, whereas an arc is an open path. So, how is the concept of open and closed paths relevant to Motion Path animations in PowerPoint?
