You can rotate objects using any of several methods.
To rotate clockwise or counterclockwise in 90° increments, click either of the Rotate buttons in the Control panel.
To rotate by preset angle, choose an angle from
the Rotation Angle pop‑up menu
in the Transform or Control panel.
In the Rotation Angle box
on the Transform or Control panel, type a positive angle to rotate
selected objects counterclockwise, or type a negative angle to rotate
selected objects clockwise, and then press Enter (Windows) or Return (Mac OS).
To create a copy of the object with the new rotation applied to the copy, type a value in the width or height fields on the Transform panel and then hold down Alt (Windows) or Option (Mac OS) as you press Enter.
When you rotate a single object, the specified value remains displayed in the Transform or Control panel. When you rotate multiple objects, the Rotation Angle is reset to 0 degrees, even though the objects are rotated.
You can use the Rotate command to rotate an object by a specific amount. This command also lets you rotate a copy of the selected object, leaving the original in place.
Choose Object > Transform > Rotate.
Double-click the Rotate tool .
Select the Rotate tool and Alt‑click (Windows) or Option-click (Mac OS) on or near the object to select a new reference point.
To preview the effect before you apply it, select Preview.
To rotate the object, click OK.
To rotate a copy of the object, click Copy.
