In this mode the point of intersection of two geometric objects (line, circle, or conic) is constructed by selecting them. The mode generates all intersections of the objects. Two lines have a unique intersection. A circle and a line have two intersection points. Two conics may have four intersections.
This mode may at first sight seem to be unnecessary. Usually, points are added using add a point mode or as a byproduct of some other interactive mode. However, under certain circumstances it can be unavoidable to use intersection mode. For instance, when the intersection of two lines is not reachable in a usual view, the lines are still listed in the Construction Text, where they can be selected and used for "intersection" mode. Another case in which meet mode is a good choice is that of ambiguities, for example when three lines pass through one point. Then meet mode is a secure way of adding a particular point of intersection.
Select two objects and create their intersection.
