Geometry *Introduction The study of the geometry of gures by algebraic representation and manip-

ulation of equations describing their positions, congurations, and separations is called Analytic Geometry.

Analytic geometry is also called coordinate geometry since the ob jects are described as n-tuples of points

(where n=2 in the plane and 3 in space) in some coordinate system.Introduction to Conic Sections and

*Conics and Circles Conic sections are the curves which can be derived from taking slices of a

“double-napped” cone. (A double-napped cone, in regular English, is two cones “nose to nose”, with the one

cone balanced perfectly on the other.) “Section” here is used in a sense similar to that in medicine or science,

where a sample (from a biopsy, for instance) is frozen or suused with a hardening resin, and then extremely

thin slices (“sections”) are shaved o for viewing under a microscope. If you think of the double-napped

cones as being hollow, the curves we refer to as conic sections are what results when you section the cones

at various angles.

Circles having equal radii are congruent.
