hered in a form we will use later; in the last five sections we will deal with subjects whose inclusion in the course is optional. Section 1.5 should be read before 1.6 and 1.7, but otherwise, and except for a few exercises, sections 1.4 – 1.8 are independent of each other.

r, that the plane is the simplest surface of all, and that a good way to construct models of others is by gluing together various pieces of paper. Our definition of surface is the mathematical elaboration of this idea.

embedded in the ambient space. Hence, the length of a curve on a sheet of paper is an intrinsic property, because it doesn´t change when we fold the sheet; but the distance in space between two points on that same sheet is not intrinsic. In this chapter we study the intrinsic properties of surfaces
