Reshape adjacent segments    To reshape a segment and adjacent segments together (if they are joined with smooth anchor points), press Command (Mac) or Alt (Windows) and drag the segment. Reshaping paths by editing anchor points A path can contain two kinds of anchor points: smooth points and corner points. Smooth point    An anchor point that connects two curve segments where the curve flows smoothly through the anchor point without a sharp change in direction. Circles and sine waves are examples of paths that have only smooth anchor points. Corner point    An anchor point where the path makes a sharp turn at the anchor point. Corner points can connect two straight segments, two curved segments, or one curved and one straight segment. Tangent lines All smooth points, and some corner points, have tangent lines pass- ing through them. Canvas displays the tangent lines when a point is selected. A corner point can have one, two, or no tangent lines.When you select a corner anchor point with two tangent lines, each tangent line can move independently. When you create paths with only straight segments, the anchor points are corner points. When you draw curved paths with the Curve, Free- hand, or Auto Curve tools, the anchor points are smooth points. Add- ing anchor points to curved segments produces smooth points. To change a smooth point to a corner point You can edit, reshape, and resize two adjoining curve segments inde- pendently by converting their smooth anchor point to a corner point. 1 With the object in edit mode, click the anchor point to reveal its tangent lines. 2 Press Tab and drag one of the handles to move one of the tan- gent lines. The tangent line pivots at the anchor point and affects only one side of the anchor point. A corner anchor point with independent tangent lines
