A line segment is removed (extended negatively) to a line that it already intersects. Then three other lines are extended to a line to which they did not originally intersect. In each case, the line to extend to is selected first.

|
The following example helps to explain the video and vice-versa.
|
|
The VIDEO shows a pattern that is similar to this one. The 1st line that is selected is the line that the 2nd line is extended to.
|
A line segment ( 2nd line ) can be extended to a point that is colinear with the line segment to be extended to ( 1st line ), but which is not actually on that 1st line segment.
|
|
The 2nd line is extended to a projection of the 1st line .
|
In this example, the order in which lines are selected is reverse to the example shown above. .
|
|
The 2nd line that is selected is the line that is extended or, in this example, the line that is truncated.
|
This example is similar to the one shown above.
|
|
The 2nd line that is selected is truncated.
|
In this example, three lines are extended to the first line that was selected.
|
|
The lines selected after the 1st are the lines that are extended.
