An intersection is the junction at grade (that is to say, on the same level) of two or more roads either meeting or crossing. An intersection may be three-way (a T junction or Y junction â the latter also known as a fork), four-way (a crossroads), or have five or more arms.
This unique symbol is used with sets but not with lines. For intersecting lines, there is no symbol that is used. The point or points at which two things meet is called their intersection. Two lines can have one point of intersection, no intersection, or an infinite number of points of intersection. The intersection of sets involves finding the items that the sets have in common. If the sets have nothing in common, then they don't have an intersection.
