To update a line, follow these steps:
Choose the Move tool ( ).
Hover your mouse over one of the line's end points with the Move tool.

In order to keep the two advantages (speed and simplicity) for which Viola and Jones first created this technique.
Step 1: (x,y)→(y,−x). ( x , y ) → ( y , − x ) A 90-degree clockwise rotation will provide the same outcome as a 270-degree counterclockwise rotation. Step 2: Rotate the rectangle by following the 90-degree clockwise rule for each point.
