Michael,
Again, the wording you use is a bit confusing to me. The "right angle distance between the 2 parallel lines"? I get what you mean by distance though. Follow the link below and click on the image there. If you use Kennedy's ear as a gauge, you should be able to approximate the distance between the two wounds. Using that photo, you can even get the vertical angle between the two wounds. That's approximating the location of the entry wound of course. 5.5 cm below the fold in the neck.

The angle between two parallel lines is either 0 degrees or 180 degrees.
On edit, I now get what you mean by "right angle distance between the 2 parallel lines".
Using that photo, you can even get the vertical angle between the two wounds. That's approximating the location of the entry wound of course. 5.5 cm below the fold in the neck. Thanks Tim I see what you mean and accept there may be various approximations of things.
In the theoretical equation I am proposing though, the next thing I am looking for, before the
vertical angle aspect, is the distance ALONG the horizontal lines between the wounds.
Then just doing that on the horizontal plane for this example equation I have a RECTANGLE you see.
What I am using for those measurements is 8 &1/2 inches by 2 & 5/8 inches.(estimating from the well known C7 photo with the ruler and 2 hands)
That was why I was looking for a few other approximates of them because what I am using are just my own approximates.
