- 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.
