The primary purpose of using transitions in PowerPoint is to control the flow and visual appeal between slides. Transitions help provide a seamless and smooth progression of slides, creating a more engaging and professional presentation. By adding transitions, presenters can fade, dissolve, slide, or animate between slides, enhancing the overall visual experience for the audience. Customizing slide backgrounds, adding animations to slide objects, and inserting audio and video clips are additional features that can also be utilized in PowerPoint, but they are not the primary purpose of using transitions.
