Rotating an object means changing the angular placement of the object.

To rotate an object;

1. Select the object.
2. Select the Rotate tool from the toolbox. The pointer changes to a star.
3. Position the star at a fixed point at the centre of the object.
4. Drag the star away from the fixed point in the direction you want to rotate the object. To rotate at intervals of 450, press the SHIFT as you drag clockwise or anticlockwise.
5. When the object is in the desired position, release the mouse button
