GeoGebra – graphing, geometry, 3D, and more

GeoGebra is an open source, multi-platform dynamic mathematics software for learning and teaching.

Specifically, this application is dynamic mathematics software for all levels of education. It joins arithmetic, geometry, algebra and calculus. It also provides multiple representations of objects in its graphics, algebra, and spreadsheet views that are all dynamically linked.

Constructions can be made with points, vectors, segments, lines, polygons, conic sections, and functions. All of the constructions can be changed dynamically. Elements can be entered and modified directly on screen, or through the command line. GeoGebra can use variables for numbers, vectors and points, find derivatives and integrals of functions and has a full complement of commands like Root or Extremum.

Teachers can also use GeoGebra to make conjectures and prove geometric theorems.

Features include:

  • Views:
    • Algebra.
    • Spreadsheet.
    • Auxiliary Objects.
    • Horizontal splitting.
  • Tool creation.
  • The Graphics View shows the graphical representation of mathematical objects (e. g., points, vectors, segments, polygons, functions, curves, straight lines, conic sections). Whenever the mouse is moved over one of these objects a description appears as a roll-over text and the object is highlighted.
  • Construction Tools:
    • General.
    • Point.
    • Vector.
    • Segment.
    • Ray.
    • Polygon.
    • Line.
    • Conic Section.
    • Arc and Sector.
    • Number and Angle.
    • Boolean Variable.
    • Locus.
    • Geometric Transformation.
    • Text.
    • Image.
