- both are conic sections ( the intersection of a cone by a plane)
- both have two directrices
- both have two foci
- the ellipse is the locus of points so that sum of the distances to the foci is constant/the hyperbola is the locus of points so that difference of the distances to the foci is constant.
- In projective geometry they are equivalent. Hyperbolas are just ellipses that cross over infinity. (imagine watching a big giant ellipse that goes off in one direction past the horizon line and then reemerges from the horizon line behind you. It would look just like a hyperbola.)
- The hyperbola is an ellipse with an imaginary semi-minor axis (a negative quare root; hence the change in sign in the hyperbola's formula)

What are the four kinds of parabolas?
Conic Sections are figures that can be formed by slicing a three dimensional right circular cone with a plane. There are different ways to do this, and each way yields a different figure. These figures can be represented on the graph as well as algebraically. The four conic sections are circles, ellipses, parabolas, and hyperbolas.

What are similarities between skateboards and cars?
They both have four wheels.
What are the similarities between a parallelogram and square?

What do four dots mean?
== == Three dots are ellipses, meaning that something is left out. If you combine ellipses with a period, then that would leave four dots... meaning that something is left out, and then it ends.
