Slide Master view shows a list of Slides on the left that are called Layouts. A layout is a special configuration of slide that can be used in our presentation for example to display a chapter title, a slide with title plus slide content, a presentation cover slide or any other custom layout that we want to consider, for example we may be interested to include a picture slide to show a picture to the audience, or a comparison slide with two columns to compare data.
