circular points at infinity

In geometry, the "circular points at infinity" are special points used in advanced mathematics to understand properties of shapes like circles and lines. They are abstract points added to the concept of infinity, helping mathematicians analyze and classify shapes consistently, especially in projective geometry. These points are called "circular" because they relate to circles, and "at infinity" because they exist conceptually far away, beyond any finite distance. They unify the treatment of circles and lines under the same framework, making it easier to study geometric properties and transformations.
