Arc (projective geometry)

In projective geometry, an **arc** refers to a specific configuration of points and lines that provides an interesting structure for studying geometric properties and relationships. More specifically, an arc can be defined as a set of points on a projective plane such that certain conditions hold regarding their linear configurations. In the context of finite projective geometries, an arc is often characterized as follows: 1. **Finite Projective Plane**: Consider a finite projective plane of order \( n \).
