To rotate the object 90 degrees to the left, select Rotate Left 90°.
To rotate the object 90 degrees to the right, select Rotate Right 90°. Select the object that you want to rotate. You can also use the arrows to rotate the object exactly where you want. In the pane or dialog box that opens, enter the amount to rotate the object in the Rotation box. Select Rotate, and then select More Rotation Options. Go to Shape Format, Drawing Tools or Picture Tools > Format. When you rotate multiple shapes, they do not rotate as a group, but instead each shape rotates around its own center. To constrain the rotation to 15-degree increments, press and hold Shift while you drag the rotation handle. Select the rotation handle at the top of the object, and then drag in the direction that you want. You may have to double-click the object to open the Format tab. Note: If you don't see the Shape Format, Drawing Tools, or Picture Tools tabs, make sure that you've selected a text box, shape, or WordArt.
