👉 In the context of geometry, a penoncile is a type of conic section that has one focus and two directrices. It is a type of ellipse with an eccentricity equal to its semi-major axis. The name "penonciles" refers to this specific type of conic section, as they are often seen in geometric shapes such as cones or spheres, where the focus and directrix are perpendicular lines that intersect at one point, forming a cone.
