Using algebra for counting angles between fixed points
I am a student at my last year in college an I am looking for a topic for an article to write. I've found geogebra and I've told myself that this program can be very useful for orthodontics analysys of x-ray photos. So there goes my (rookie i guess) question - is it possible for this program to count angels between fixed points (which would be placed randomly) and then export them into a table ?
Thank you very much for all the answers !
