👉 In geometry, a "circular curve" is defined as a smooth curve that has one or more points on it where any two adjacent points have the same distance from each other. This distance is called the radius of curvature at that point. The shape of a circular curve can be described by its equation in the form y = ax + b, where a and b are constants. Circlines are important shapes in mathematics, physics, and engineering because they provide insights into the behavior of objects
