Definition
Adjacent is a term used to describe a situation where two objects, locations, or areas are close to each other but are not necessarily touching. This concept is prevalent in various fields such as geometry, real estate, urban planning, and everyday spatial relationships.
Examples
- Geometry: In a polygon, adjacent sides share a common vertex, but not necessarily a common length.
- Urban Planning: Two adjacent buildings may be separated by an alleyway or small park.
- Real Estate: A house may be adjacent to a commercial area, meaning it is close by but not in the same block.
- Desks in an Office: Two desks are adjacent if they are near each other within the workspace, even if they aren’t touching.
Frequently Asked Questions (FAQ)
Q1: Is ‘adjacent’ the same as ’next to’?
- A1: Not necessarily. ‘Next to’ implies that the objects are in physical contact, while ‘adjacent’ only means they are nearby or close.
Q2: Can two objects be considered adjacent if there is a small gap between them?
- A2: Yes, the term ‘adjacent’ allows for a small gap or distance between two objects, as long as they are relatively close.
Q3: Is being adjacent always related to physical proximity?
- A3: Typically, yes. However, the term can also be used metaphorically in contexts such as topics or concepts that are closely related but not exactly the same.
Q4: What is an example of adjacent angles?
- A4: Adjacent angles are two angles that share a common side and a common vertex, but do not overlap each other, like two angles on a geometric shape that touch at a single point.
Related Terms
- Contiguous: Refers to objects that are touching or sharing a common border.
- Proximal: Indicates that something is nearer to a point of reference.
- Vicinity: A surrounding area or neighborhood, implying nearness.
- Neighboring: Located or situated nearby; can imply a slight separation.

Fundamentals of Adjacent: Geometry Basics Quiz
### What does 'adjacent' mean?
- [ ] Exactly the same
- [x] Nearby, but not necessarily touching
- [ ] Across the street
- [ ] Intersecting
> **Explanation:** 'Adjacent' refers to objects that are nearby but not necessarily in physical contact with each other.
### In geometric terms, what are adjacent angles?
- [x] Two angles that share a common side and vertex
- [ ] Two angles that are equal
- [ ] Angles on opposite sides of a polygon
- [ ] Angles that add up to 180 degrees
> **Explanation:** Adjacent angles share a common side and vertex without overlapping.
### Can two rooms in a house be adjacent even if there’s a hallway between them?
- [x] Yes
- [ ] No
- [ ] Only if the hallway is very short
- [ ] It depends on the rooms’ use
> **Explanation:** Even with a hallway in between, the rooms can still be considered adjacent as they are nearby.
### Which term is the closest synonym for adjacent?
- [x] Neighboring
- [ ] Opposite
- [ ] Identical
- [ ] Separate
> **Explanation:** 'Neighboring' best captures the essence of objects being close but not necessarily touching.
### Identify a scenario which best describes 'adjacent'.
- [ ] Two circles overlapping
- [x] Two rows in a classroom seating plan
- [ ] Two rooms at opposite ends of a building
- [ ] Two countries that are separated by an ocean
> **Explanation:** Two rows in a classroom are near each other without necessarily being in direct contact.
### How might an urban planner describe two parks that have a street between them?
- [x] Adjacent parks
- [ ] Connected parks
- [ ] Separate parks
- [ ] Distant parks
> **Explanation:** The parks are nearby with a small division, making them adjacent.
### Which of the following pairs can be adjacent?
- [ ] North and South Poles
- [x] Two neighboring countries
- [ ] East and West ends of a town
- [ ] Top and bottom of a ladder
> **Explanation:** Two neighboring countries can be described as adjacent due to their close proximity.
### What is another example of adjacency in daily life?
- [ ] Two people sitting on opposite sides of a stadium
- [ ] A person and their shadow
- [x] Bedrooms separated by a wall
- [ ] A beach and a desert
> **Explanation:** Bedrooms separated by a wall are adjacent since they are close without direct contact.
### In real estate, how might 'adjacent' be used to describe a property?
- [x] A home next to a park with a street in between
- [ ] A commercial lot far from residential properties
- [ ] Houses within the same gated community
- [ ] Buildings on the same block but different streets
> **Explanation:** A home next to a park with a street in between effectively demonstrates adjacency.
### Why is the concept of 'adjacent' important in geometry?
- [ ] It complicates understanding of shapes
- [ ] It creates confusion
- [ ] It distinguishes proximity in spatial relationships
- [ ] It changes the properties of shapes
> **Explanation:** Adjacency helps in understanding spatial relationships and properties of shapes.
