How do you add a transition effect to slides?

To add a transition effect to slides in PowerPoint, you need to select the specific slide you want to apply the transition to, navigate to the Transitions tab on the ribbon, and then choose the desired transition effect from the options provided. This process allows you to preview the selected transition directly and apply it effectively to the current slide. The Transitions tab is specifically designed for this purpose, offering a variety of effects that can enhance the presentation by providing visual movement between each slide.

The other methods described are not the standard way to apply transitions. For example, right-clicking and selecting Transition may suggest accessing a context menu, but this function typically does not provide access to the full range of transition options available in the Transitions tab. Similarly, going to the File tab is primarily used for managing document settings rather than editing slide characteristics. Finally, using the Animation tab is meant for adding animations to elements within a slide rather than transitions between slides. Therefore, the correct method emphasizes the importance of using the dedicated Transitions tab for adding and customizing transitions effectively.
