Choosing the Edit Points option in PowerPoint transports you to a mode in which PowerPoint works more as an illustration program such as Adobe Illustrator than like a normal slide program. In this mode, PowerPoint lets you control how a shape looks. Sometimes you might find it difficult to edit a certain segment in a shape because there are no vertexes (points) available to manipulate — or maybe there are far too many points! PowerPoint provides a simple solution for this problem — you can add and remove vertexes in a shape, as explained in these tutorials:
