Parallel lines with a transversal
I want to create a pair of parallel line segments with a transversal going through them.
I want to create a pivot point so that the user can rotate the parallel lines together.
I want the user to be able to move the parallel lines closer and further away from each other.
I also want to be able to create 8 check boxes that allow users to hide/reveal the value of the 8 angles created by the parallel lines and the intersecting transversal.
I want to keep AB parallel to DH (image attached)
How do I do these things? Thanks a lot
