Quadratic Curves

So far, we have limited ourselves to the lines which are thoroughly studied at school: namely, straight lines and circles. All the propositions of our “alphabet” from A to J involved only these. In this chapter we are going to learn about some other curves: ellipses, hyperbolas and parabolas. Taken together, these curves are called conic sections or simply conics, since they may all be obtained as the intersection of a plane with the surface of a cone, as is shown in the figure on pp. 76–77.
