Takes a bit of getting used to, but is a powerful visualization tool

I recently came to GeoGebra having a background in design, not mathematics. I explore mathematical relationships of circles, polygons, etc out of curiosity and for integration into artwork. Apps like Blender and Inkscape, while great for design, do not offer mathematical precision for analyzing geometric relationships. I needed software that was visually oriented yet more specialized for math and in GeoGebra I found it. At first I gave this a 3-star rating because of initial frustration. After getting to know this app a bit better I feel it deserves more like a 4 or 5.

My initial frustration was partly valid - the interface and construction tools could be implemented better. However I admit that half of my frustration was due to my expectations of how such an app should function and wanting it to behave in a way that is more visually intuitive versus how it actually behaves which is more mathematically exact. For example, I am used to being able to freely scale or rotate any geometric form in the design apps I use. In GeoGebra if you want to scale or rotate your construction you must change the value of the underlying shape that the rest of the construction is based on, and this may require changing how your construction is built. Also shapes can have dependencies in the sense that deleting a shape can cause other shapes it was derived from to also be deleted. I did not see the logic in this, but after discovering there is a feature that allows for all the steps of construction to be viewed in a sequence I now can appreciate that this app aims to preserve the exact recipe for how forms are constructed, and mathematically that is more valuable than being able to simply transform any shape on a whim.

I still wish for better snapping implementation, a quick tool for generating inscribed or circumscribed geometry, more keyboard shortcuts, and the fixing of various annoyances like having to hide a polygon before you can select whats underneath it. But over all this is a great app. Where it could use improvement is in the interface and usability. Mathematically speaking it has been great for me and allowed me to take measurements with precision that was heretofore impossible for me using other software. I have also learned a few mathematical formulas as a result of using this. So for that I have to give it 5 stars. Being free and open source is also a huge plus. It does have some bugs and quirks but there is no other software like it that can compare.
