Click the Align pop-up menu, then choose an option.
If one object is selected, it aligns to the slide. If two or more objects are selected, the objects align to the object most in the direction you selected. For instance, if you align three objects to the left, the leftmost object doesn’t move, and the other objects align to it.
You can position objects so there is equal spacing between them on a horizontal or vertical axis, or on both axes.
