Brian needs to see the space available to insert content on a slide in his presentation which feature of the presentation should he use

The feature that Brian should take advantage is Layout, which is available in his presentation, to insert the content he wants, be it a graph, picture, paragraph, bullet points, video, etc. Assuming this is a Microsoft PowerPoint, Brian can right-click the slide he wants to put the content in, where an option window would appear.
