Any given shape in PowerPoint is essentially an electronic drawing that is composed of both segments and points (vertexes). Think of a “connect-the-dots” drawing and the dots would be points, and the lines you draw between the dots would be segments. Both segments and vertexes are only visible as distinctly different drawing elements only in Edit Points mode. We discuss more about segments in a subsequent tutorial but for now, let us help you explore the different types of vertexes (points) in PowerPoint 2011. Essentially, these are of three types: Smooth, Straight, and Corner.
