👉 In geometry, a "beltline" is a line connecting two points on a straight line or curve. This concept arises from the idea of a series of points that can be joined together to form a continuous path. The beltline connects two points along a straight line or a curve. It is often used in geometric constructions and modeling, especially when working with curves like circles, ellipses, and parabolas. The beltline serves as a reference point for the construction of these shapes,
