Any of the tools we have already looked at for adjusting straight lines apply to curved lines and shapes. You can add and remove anchor points, and adjust points (and the resulting lines) using the direct selection tool. Create a shape with curves and practice making adjustments with these tools.
In addition, you can adjust the slope and angle of curves by changing the “direction lines,” which are the straight lines extending from anchor points. To adjust the curve, select the direct selection tool. Click an anchor point to show the direction line for that point and adjacent points. Then, click and hold on a blue square at the end of a direction line, and drag to adjust the curve. You can also click an anchor point and drag to move the point, which will also extend all curves connected to that point.
