It means that they intersect and share a common point.
The intersection.
In Euclidean geometry, any two lines in a plane that are not parallel will cross.
Intersecting lines
They would 'intersect'. ('cross', have one point in common)
A common intersection.Lines that cross at one point are called intersecting lines. One of the defining characteristics is that one line will have a positive slope and the other will have a negative slope.
Intersecting lines are lines which cross each other at at least one point.
It means that they intersect and share a common point.
The intersection.
point I believe the word you're looking for is "intersection". Two non-parallel lines that lie in the same plane will have one point in common where they cross, and that point is the intersection.
Intersecting lines are lines that meet at a point. In other words lines that cross each other (like an X).
Intersecting lines are lines that meet at a point. In other words lines that cross each other (like an X).
An intersection is the point at which two or more lines touch or cross, therefore, lines are intersecting when they cross each-other.
In Euclidean geometry, any two lines in a plane that are not parallel will cross.
In Euclidean geometry, any two lines in a plane that are not parallel will cross.
Intersecting lines
If two lines cross they share a point of intersection. For two straight lines this is limited to one common point, for two circles two points and for complex lines like two sine waves the number of common points has no limit.
