# Conic Section Conic sections are shapes that are produced when a doubled cone is intersected with a plane. They are the [[Ellipse]], the [[Circle]], the [[Quadratics|Parabola]], and the [[Hyperbola]]. ^izsam9 ![[dmhn7XlmF1-conics.svg.png]] All conic sections can be also be described as collections of points for which the following is true: $Ax^2 + Bxy + Cy^2 + Dx + Ey + F = 0$ The type of the conic section is determined by the values $A$, $B$, $C$, $D$, $E$, and $F$.
