👉 Evolute is a geometric figure in mathematics that represents the shape of a curve or line when it is rotated around its center. It is also known as an ellipse, which is a type of conic section. Evolute is a special case of a hypocycloid and can be defined as the curve traced by a point on a circle after being rolled along a straight line with a small circle at each end. Evolutes are frequently used in geometry for creating more complex shapes or to study the
