Do one of the following:
•
To change the length of one of the tangent handles independently from the other,
while keeping the angle of both handles locked relative to each other, drag a handle
to lengthen or shorten it. You can also rotate both handles around the axis of the
selected point.
•
To change the angle of one of the tangent handles relative to the other, along with
its length, press the Command or Control key while dragging a handle around the
axis of the selected point. The selected tangent handle moves, but the opposing
tangent handle remains stationary.
•
To keep the angle of both tangent handles at 180 degrees relative to one another,
keeping the lengths of each side of the tangent identical, press the Shift key while
dragging either of the tangent handles around the axis of the selected point. If you
Shift-drag tangent handles that were previously angled, they are reset.
