I found that disturbing and fascinating and wanted to “prove it,” which I eventually did using just two medians, making a midpoint-to-midpoint line segment, and then considering (what else?) similar triangles.īut then I wanted to see it on a computer program (and using BASIC to make graphics is disgustingly no longer a viable option in this day and age), and I tried Desmos but that was brutal (you have to come up with 6 line segment equations for each triangle). A great (to me) theorem I came across says that for any triangle, the medians (midpoint-to-vertex) will all intersect and will be partitioned by that intersection into 2 segments, and those segments will have a 2:1 length ratio. I’m going through Schaum’s Outline of Geometry, working many of the exercises. IPad user/Physics major re-studying geometry for fun I encourage the developers to either support iOS or not… but don’t make a frustratingly incomplete app.

In the support forums I see years of people complaining about this inability to save files.

ggb file… but then when I went through the ridiculous workaround to open it, the file was corrupted and didn’t even remotely contain what I started with. It didn’t work for me: I used the “share” menu, exported it to files, and ended up with a. Sure, if you look online, after extensive searching you will find various people explaining workarounds for how you can supposedly save your work, but you will find just as many people complaining that it doesn’t work right. But! The iOS version is useless for anything other than quick and dirty sketches because *you still can’t reliably save your work even after all these years*. It’s smooth and useful for all sorts of purposes, such as understanding geometry proofs, definitions of conic sections, or just playing around. No way to save files… after all these years!įirst off, Geogebra is an awesome system and the Geometry engine is a masterpiece.
