Which tab in PowerPoint allows you to insert the shapes ?

Concept: PowerPoint's ribbon groups every command by the job it performs. The Insert tab holds all commands that add new content — shapes, images, tables, charts, and text boxes — onto a slide, while the Review, Design, and View tabs each handle a different job (proofing, appearance, or display) rather than adding objects.

Application: A shape is new content being added to the slide, so the Shapes gallery sits inside the Insert tab, in its Illustrations group (Insert > Illustrations > Shapes).

Cross-check: Contrasting the other tabs by what they actually contain confirms this by elimination:

• Review groups proofing and collaboration commands — Spelling, Comments, Compare — for checking content, not adding it.

• Design groups appearance commands — Themes, Variants, Slide Size — for styling a presentation, not adding objects.

• View groups display-mode commands — Normal, Slide Sorter, Notes Page — for changing how slides are viewed while editing, not adding objects.

Result: Only the Insert tab groups object-creation commands, so it is the tab that lets you insert shapes.
