Copy the 3 lines.

Scale them by the ratio of the distances CD/AB

Use align to position the scaled copies along the line passing through CD.

 

 

Or use trim!  Is there more to your question?

Are you wanting  a manual out of box answer or a program to do it, do you know anything about Lisp in particular the VL function "Intersectwith".

Do the vertical lines exist or are they there only to indicate the intersection points ? I ask as you can have just single lines and use the end points to make temporary lines that are vertical and as suggested "Intersectwith" does just that intersection of 2 objects.
