Add or delete anchor points
Adding anchor points can give you more control over a path or it can extend an open path. However, it’s a good idea not to add more points than necessary. A path with fewer points is easier to edit, display, and print. To reduce the complexity of a path, delete unnecessary points.
The toolbox contains
three tools for adding or deleting points: the Pen tool 
, the Add Anchor Point tool 
, and
the Delete Anchor Point tool 
.
By default, the Pen tool changes to the Add Anchor Point tool as you position it over a selected path, or to the Delete Anchor Point tool as you position it over an anchor point.
Note: Don’t
use the Delete, Backspace, and Clear keys or the Edit > Cut or
Edit > Clear commands to delete anchor points; these keys and
commands delete the point and the line segments that connect to
that point.
