In mathematics, the term “adjacent” is commonly used to describe objects or elements that are next to each other or in close proximity. This term is especially relevant when discussing geometric shapes and angles.

In the context of geometry, two line segments or rays are considered adjacent if they share an endpoint and lie on the same line. For example, if line AB and line BC both share the point B and lie on the same line, then line AB and line BC are adjacent.

Adjacent angles, on the other hand, refer to two angles that share a common vertex and a common side. The common side is typically a ray or a line segment, while the common vertex is the point where the two sides of the angle meet. For instance, if angle PQR and angle QRS share a common side QR and a common vertex Q, then angle PQR and angle QRS are adjacent angles.

It’s important to note that adjacent angles do not overlap. They can only share a common side and vertex, but their interiors should not intersect. Additionally, adjacent angles can be complementary, supplementary, or have other relationships depending on their measurements and properties.

Overall, the concept of adjacency is crucial in geometry as it helps define the relationship between different geometric objects and enables us to analyze their properties systematically.
