There is an infinite number of places to draw lines in the video. You first have to figure out where you want lines. Once you know that you'll be able to find the intersection points of the lines using simple algebra.

I have given the sample image and sample lines please give me some examples how to draw those lines and is there any ways to make the video lebeling tool box lines parallel to each other
