Commensurability (mathematics)

In mathematics, the term "commensurability" often refers to a relationship between two or more mathematical objects, indicating that they share a common measure or can be expressed in terms of one another in a way that involves a rational relationship. Here are a few contexts in which commensurability is often discussed: 1. **Geometry**: In the context of geometry, two line segments are said to be commensurable if their lengths can be expressed as a ratio of two integers.
