An intersection is a point where two lines or streets cross.

There are two places you're most likely to find intersections: in math class and in traffic. In math, an intersection is the spot where two lines cross. Those lines share this common point. The center of the letter X is an intersection. The same is true for streets: the intersection of Clark and Huron is where those streets cross. From the intersection, you can choose to travel down either street. When you're trying to get somewhere, it's helpful to know the major intersections.

Definitions of intersection

n the act of intersecting (as joining by causing your path to intersect your target's path)

Type of:
connection, connexion, joining
the act of bringing two things into contact (especially for communication)

n a point where lines intersect

intersection point, point of intersection
metacenter, metacentre
(shipbuilding) the point of intersection between two vertical lines, one line through the center of buoyancy of the hull of a ship in equilibrium and the other line through the center of buoyancy of the hull when the ship is inclined to one side; the distance of this intersection above the center of gravity is an indication of the stability of the ship
the point of intersection of lines or the point opposite the base of a figure
Type of:
a geometric element that has position but no extension

n a junction where one street or road crosses another

carrefour, crossing, crossroad, crossway
corner, street corner, turning point
the intersection of two streets
grade crossing, level crossing
intersection of a railway and a road on the same level; barriers close road when trains pass
blind corner
a street corner that you cannot see around as you are driving
Type of:
the place where two or more things come together

n the set of elements common to two or more sets

“the set of red hats is the intersection of the set of hats and the set of red things”
Cartesian product, product
Type of:
a group of things of the same kind that belong together and are so used

n a point or set of points common to two or more geometric configurations

the point of intersection of coordinate axes; where the values of the coordinates are all zero
Type of:
(mathematics) an abstract collection of numbers or symbols

n a representation of common ground between theories or phenomena

convergence, overlap
a point where a choice must be made
the overlap where two theories or phenomena affect each other or have links with each other
Type of:
internal representation, mental representation, representation
a presentation to the mind in the form of an idea or image
