Geometry diagrams Dear MyMathForum friends, I was wondering what you use to create diagrams when submitting geometry solutions. I know $\LaTeX$ but I don't know how to create diagrams. For example, I see these complicated geometry diagrams people submit to Mathematics Magazine, but I'm not sure how to create them. Does anyone know?

Thank you. I see people turning in diagrams like the one attached and always wondered how they did it.

I always found it a pain though. Another option (which depends on what/how you're drawing something) is to just write little scripts in R or Julia or whichever language has decent graphic capabilities (Python, MATLAB...). I mention R though because you can get high def plots using ggplot and there are a lot of options. The downside is that it is not a "click and drag" format like Geogebra and you'll need to come up with numerical values for everything you plot. Last edited by skipjack; July 19th, 2019 at 10:39 AM.
