In Microsoft PowerPoint, the ruler itself does not provide a rotation function. Rulers are used to help users align objects such as text and graphics, as well as to measure and set the position of objects on a slide. If you need to reorient an object, you should use the Rotate tool to rotate the object, not the ruler. Here are the basic steps on how to rotate an object in PowerPoint:
Select the objectFirst, click on the object you want to rotate, such as a text box, a shape, etc.
Use the rotating handle: When you select an object, you'll see a marquee appear around the object with a rotation handle (a small green dot) above the marquee. Place the mouse pointer over the rotation handle and the mouse pointer will turn into a rotation icon.
Drag to rotate: Hold down the rotation handle and drag the mouse, and you can rotate the object freely. If you need to rotate at a specific angle, such as °, you can hold it down while draggingshiftkey, which causes the object to rotate in 15° increments.
In addition to dragging the rotation handle directly, you can also use the rotation function in the Format tab for more precise control
Select the object: Click on the object you want to rotate.
Open the Format tab: In the menu bar of PowerPoint, select the Format tab.
Click "Rotate".: In the Format tab, find the Rotate button in the Arrange group. Clicking on it will bring up a drop-down menu that offers several rotation options, including "Rotate 90° to the right", "Rotate 90° to the left", "Flip Vertically", and "Flip Horizontally". In addition, you can select "More Rotation Options" for more detailed settings.
The PowerPoint ruler is used to aid positioning and alignment and cannot be rotated.
When you rotate an object, the object's position and alignment may change, and you may need to use rulers and guides to realign the object.
If your purpose is to adjust the orientation of the view or action interface, rather than rotating the object, this usually involves adjusting the display settings or the orientation of the slides, rather than manipulating inside PowerPoint. Hope you find this information helpful!
