Relation( <List> )
Shows a message box that gives you information about the relation between two or more (up to 4) objects.
Relation( <Object>, <Object> )
Shows a message box that gives you information about the relation between two objects.
This command allows you to find out whether
  • two lines are perpendicular
  • two lines are parallel
  • two (or more) objects are equal
  • a point lies on a line or conic
  • a line is tangent or a passing line to a conic
  • three points are collinear
  • three lines are concurrent (or parallel)
  • four points are concyclic (or collinear).

Some of these checks can also be performed symbolically. If GeoGebra supports symbolic check for a certain property, the "More" button appears. By clicking it, GeoGebra may provide more information whether the property is true in general (eventually under certain conditions).

Note: See also Relation tool.
