Answer 2

Answer:

A slide transition is how one slide is removed from the screen and the next slide is displayed during a presentation. PowerPoint offers many entertaining and different slide transition schemes- the trick is to be careful not to use too many different schemes in one presentation. Be selective and consider the appropriateness of the scheme before you apply it to the different slides. Test them out by running the Slide Show and evaluate them for effectiveness. Quality rather then quantity is the key.
