An ellipse is a closed curve on a plane surrounded by two foci. It is a type of conic section, derived from the intersection of a cone and a plane. A key characteristic of ellipses is their symmetry, with their shapes often resembling an elongated circle. The major axis, the longest diameter, is a focal point of the ellipse, and the distance from any point on the ellipse to the two foci remains constant. This property makes ellipses useful in various mathematical applications, including physics and engineering.

• Students: Middle school to high school students, particularly those preparing for advanced math exams.
