GeoGebra Geometry

Ok, now this is probably the most pointless thing I have ever done with my students. This app is making me crazy with the controls and I am very disseapointed in this app and how it turned out. So I gave u a 1

Badly needs basic functionality like saving, and logging into the GeoGebra site. 2 years on and there STILL isn't a save function.

The most tedious, frustrating and useless app I have ever had the displeasure to use. Making congruent shapes is a nightmare, the controls are confusing, and the settings menu is an endless labyrinth of pointlessness. Don’t download if you wish to remain a happy and sane human being.

然件非常好用，但能不能在几何区增加一个数据的处理功能，如角与角的和等，谢谢

不会用

我想用滑动条旋转一个角，就是一度一度的转，但是我那里滑动条只显示数字，都不能搞度数的。我下这个就是能够更好的理解数学题，结果你连转角度都不行

①极轴捕捉 ②画等长线段 ③画等角

怎么找轨迹

怎么保存图像

希望开发出保存功能，可以存储画好的图就完美了
