GeoGebra 4.0 Sneak Peek: Part I – New Tools

This is the first part of the GeoGebra 4.0 Sneak Peek Series. In this series, we are going to discuss some of the changes in GeoGebra from version 3.2 to 4.0. If you want to have a complete view of the changes, you can read the GeoGebra 4.0 Release Notes.

If you don’t know yet, GeoGebra 4.0 will be released by the end of August this year in a few weeks . If you’re as excited as me and want to try out the new features, you might want to explore the GeoGebra 4.0 Beta release.  This release is, of course, not stable (they may still change some features).

The most evident changes in GeoGebra 4.0 are the new tools. The tools, their icon, and their descriptions are shown below.  Some tools have no icons yet, so I left it blank. 

Icon Name Description
Attach/Detach Point Attaches/detaches a point to a particular object.
  Function Inspector Displays different properties of functions (maximum, minimum, roots, etc). We will discuss this in a separate post.
  Insert Button Inserts a command button in the GeoGebra drawing pad.
  Insert Input box Inserts a text box in the GeoGebra drawing pad for inputs.
Pen Tool Enables writing/drawing on the drawing pad.
Point on Object Creates a point on a region or a perimeter of a region.
Polyline Creates a series of segments.
Probability Calculator Computes/graphs different probability distributions.
Rigid Polygon Creates a polygon that you can translate or rotate, but can’t change its shape.
Vertex Polygon Creates a polygon that you can translate or rotate, but can’t change its shape.
Complex Number Creates a point with coordinates x + yi
Create List Creates a list of objects

If you want to explore these tools, just download the  GeoGebra 4.0 Beta release and tinker with it.

In the next post, we are going to see some major changes in GeoGebra’s user interface.
