Intersect Tool
From GeoGebra Manual
- Intersection points of two objects can be created in two ways (also see command Intersect).
- Selecting two objects creates all intersection points (if possible).
- Directly clicking on an intersection of the two objects creates only this single intersection point.
- Note: For segments, rays, or arcs you may specify whether you want to Allow outlying intersections on tab Basic of the Properties Dialog. This can be used to get intersection points that lie on the extension of an object. For example, the extension of a segment or a ray is a straight line.
Comments
Use "Point Tool" for intersection[edit]
There is an other possibility to get an intersection point of two objects:
- Use the
Point Tool and click directly on the (not yet existing) intersection point.
This is a possibility to get only one of two intersections of two circles, so that you have one point less. But it is not always working as wanted.

Try to change the option of the continuity behaviour of GeoGebra, if the selected intersection point position does not behave as wanted. Some more information here |
