Rotating a polygon within a PDF depends on the software you are using to view and edit the PDF. However, based on the reference provided, here's one specific method:
To rotate a shape (likely including polygons) within a PDF using a trackpad gesture:
- Open the PDF: First, open the PDF document you want to modify.
- Select the Shape: Choose the polygon you want to rotate. The method for selecting the shape will vary based on your PDF editor, but often involves a selection tool.
- Rotate with Trackpad: Once the polygon is selected, place your thumb and a finger on the trackpad. Pivot your fingers around each other (similar to turning a jar lid) to rotate the shape.
Keep in mind that this method is specific to certain PDF viewers/editors and their interface. Different PDF editors may use different approaches for rotating objects. Check the documentation or help resources for your specific software for precise instructions. Some software requires you to enter an edit mode or choose a rotate tool before you can rotate the polygon.
