Rotate and modify shapes added to a PDF
Rotate a shape: Select the shape and place the pointer over it, place your thumb and a finger on the trackpad, then pivot them around each other as if you’re turning a jar lid. You can even Shift-click to select multiple shapes and rotate them together.
Change a shape’s sides and angles: For some shapes (stars and hexagons, for example), you can change the number of sides and angles. Select the shape, then drag one of the green handles.
