Circles , parabolas , ellipses and hyperbolas are conic sections and have many unique properties . The properties of the tangents to conic sections prove quite interesting . Dandelin spheres are tangent to ellipses inside a cone and support the geometric definition of an ellipse . Tangent lines to parabolas , ellipses and hyperbolas in the form of families of folds are shown to create conic sections in unique ways . The equations of these tangent lines to conic sections and their equations can be found without using calculus . The equations of the tangent lines are also used to prove the bisection theorem for all conic sections and prove uniqueness for the bisection theorem in connection to conic sections . |
