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.
