Lecture 20 (Geometry) Analytic Geometry and Equations of Lines

Intuitively, what is analytic geometry?

1. A.Combining numbers with geometry by coordinatizing the plane and representing geometric figures with equations.
2. B.The study of solid figures using only compass and straightedge constructions.
3. C.A method of proving theorems using only the postulates of planar geometry.
4. D.The study of shapes preserved under continuous deformation.
