👉 Radicles, also known as branch points or point of tangency in mathematics and physics, are a type of boundary that is used to describe the boundaries of a set of points. They are defined by a circle that lies outside the set being described. In mathematical terms, a radicle is an endpoint on the circumference of a circle where the radius of the circle intersects with a line segment that goes through the center of the circle and extends to infinity. The point of tangency between two circles is
