Geometric Objects

GeoGebra works with many types of geometric objects

• Points and Vectors
• Lines and Axes
• Conic sections and Arcs
• Functions
• Curves
• Inequalities
• Intervals

Paths

Lists of points, loci, and some of the above mentioned objects (lines, conic sections, arcs, polygons, functions, single variable inequalities, intervals) are referred to as paths. One can define a point to belong to a path using the Point Command. Each point on a path has a path parameter, which is a number ranging from 0 to 1. To get this parameter, you can use the PathParameter Command.

Note: Lists of other paths are also paths.

Regions

You can also restrict points to a region (polygon, conic, arc, two variable inequality) using the PointIn Command or Point on Object Tool.

Note: See also Attach / Detach Point Tool.
