Understanding Anchor Points and Handles
               An anchor point marks the end of a line segment, and the point handles determine the shape of that segment. That’s

               Each segment in a path has two anchor points, and
                                                              It’s important to understand that every line segment is
                                                              connected to two handles. In this example, Handle A1 and
               can have two associated handles.
                                                              Handle B2 determine the shape of Segment AB. Dragging
               You can create corner points by simply clicking with the
                                                              either handle affects the shape of the connected segment.

               not have their own handles; the connected segments are
               controlled by the handles of the other associated points.

               to convert it to a corner point; click and drag from a corner   A1  AB          B2

                                                              When you use the Pen tool, clicking and dragging a point
                                                              creates a symmetrical (smooth) point; both handles start out
                                          Corner point        at equal length, directly opposite one another. Changing the

               Handle A1. We then clicked and dragged to create Point B   the length of one handle without affecting the length of the

               curve. Notice the difference in the curve here, compared to
               the curve above. When you drag a handle, the connecting
               segment arcs away from the direction you drag.
