# Geometric Objects

From GeoGebra Manual

## Types of Geometric Objects

GeoGebra works with many types of geometric objects

## 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.
