You can resize any object. You can rotate or flip any object except a table or chart.
Select an object, then do one of the following:
Resize an object: Drag a white square on its border.
Resize an object and maintain its proportions: Hold down the Shift key as you drag any white square.
Resize an object to specific dimensions: Click the Arrange tab at the top of the sidebar on the right. In the Size section, enter values or click the arrows in the Width and Height fields. If you don’t see a sidebar, or the sidebar doesn’t have an Arrange tab, click 
in the toolbar.
If you want to always constrain proportions while resizing a selected object, click the Arrange tab in the sidebar, then select the “Constrain proportions” checkbox.
Select the object, then click the Arrange tab at the top of the sidebar on the right.
If you don’t see a sidebar, or the sidebar doesn’t have an Arrange tab, click in the toolbar.
Drag the Rotate wheel, or enter a degree value in the adjacent field to specify the angle at which you want to rotate the object.
Tip: You can also press the Command key while your pointer is over a white square on the object, then drag to rotate.
Select the object, then click the Arrange tab at the top of the sidebar on the right.
If you don’t see a sidebar, or the sidebar doesn’t have an Arrange tab, click in the toolbar.
Click a Flip button (near the Rotate wheel) to flip the object vertically or horizontally.
Tip: You can add these buttons to the toolbar: Flip Horizontal and Flip Vertical.
