- The intersection of two given sets is the set that contains all the elements that are common to both sets. The symbol for the intersection of sets is "∩''. For any two sets A and B, the intersection, A ∩ B (read as A intersection B) lists all the elements that are present in both sets (common elements of A and B).

Memorize the definitions of intersection, union, and set difference. We rely on them to prove or derive new results. The intersection of two sets A and B, denoted A ∩ B, is the set of elements common to both A and B. In symbols, ∀x ∈ U [x ∈ A ∩ B ⇔ (x ∈ A ∧ x ∈ B)].

Certainly the most common, controlled intersections are intersections directed by signage or traffic lights. These are easy to know how to proceed as long as you know the basic right-of-way road rules as well. To help, we’ll go over some of the most common controlled intersections and how to proceed accordingly. Traffic Lights Probably the most fam...
Uncontrolled intersections are more likely in residential areas. These intersections have no signage or lights and are typically found in low traffic areas. As you approach an uncontrolled intersection, slow down and watch for surrounding traffic, pedestrians, and cyclists, and scan the intersection from left to right. When a vehicle has arrived at...
Often dreaded or at the very least, a source of confusion, are roundabouts. These larger traffic circles are often found in busier areas and usually have multiple lanes. It is important to know where you are going to choose the correct lane before you enter the roundabout. Look for lane use signs and markings are displayed as you approach. Always e...
Contrary to popular belief, there is a difference in traffic circles versus roundabouts. Traffic circles are the less overwhelming cousins of roundabouts: smaller in size and often found in residential neighbourhoods. When approaching traffic circles, be cautious and slow down. If any signs are present, be sure you obey those before proceeding. If ...

The intersection of two given sets is the set that contains all the common elements of both sets. The symbol for the intersection of sets is " ∩''. Learn more about the intersection of sets with concepts, definitions, properties, and examples.
Definition: The intersection of two sets, X and Y, is the set of elements that are common to both X and Y. It is denoted by X ∩ Y, and is read “ X intersect Y “. So the intersection of two sets is the set of elements common to both sets. Let’s look at some more examples of intersection.
Intersecting lines definition. Intersecting lines are two or more lines that are coplanar to each other and meet at a common point. The three pairs of lines shown above are examples of intersecting lines.
Intersection is one of the basic concepts of geometry. An intersection can have various geometric shapes, but a point is the most common in a plane geometry. Incidence geometry defines an intersection (usually, of flats) as an object of lower dimension that is incident to each of original objects.
