1. Easily construct triangles, drag points, draw parallel lines, intersect circles, save and share your results.
2. Millions of people around the world use GeoGebra to learn mathematics and science. Join us!
3. We’d love to hear from you: send us your questions or feedback via Twitter @geogebra or to support@geogebra.
1. Ability to minimize the tool menu while still using a tool! More integrated layer functionality An easy way to redefine an object by it's position, staying in the same place but detaching from any connected constructionGreat app! Just unfortunate, it gets reseted sometimes, and all my settings and work just vanishes.
2. It is EXTREMELY recommended to include "disable labelling for ALL points", "set ALL points to desired state upon drawing without having to click them manually after finish drawing geometry or clicking them one by one", "set ALL circles to desired state upon drawing as well", and PLEASE FIX the colors.
3. It has some kinks, like the settings randomly jumping back to defaults, and not being able to manually adjust the awkward positioning of labels... But on the whole, it's the best app that I've found of its type.Does what it says.
4. Sketchometry (web version) is much easier to get started with, but its drawing tools are put away in inconvenient, non-intuitive fragments, making you click a lot hence-and-forth.Sorta works.
5. It's a pain when the colors don't automatically mix when colored lines cross each other or solid circles overlapped on SAME layer.I literally taught myself trigonometry using this app.
6. Other than that, this is great!Seems like a powerful package for visually constructing calculations, but it's got a learning curve: you can't just click somewhere, but have to really know what you're doing with that click.
7. Undo button makes the screen jump around it also doesn't actually undo anything (at least I haven't been able to consistently make it do that).
8. I can no longer load my saved files without it crashing, and sometimes the undo button crashes the app, and sometimes it just crashes randomly.
9. Please, my eyes! More customization, such as saving multiple custom settings, and custom tool groups.
10. Measuring angle between three points works but doesn't when selecting two segments.
11. I would love to see an image overlay feature added so we can place maps behind the grid, then we can draw/trace/plan shapes atop of them.
