We end the chapter defining projective space and proving a weak version of Bézout’s theorem.

In the second section, we show how to extend this theory to closed semi-algebraic sets using the triangulation theorem proved in Chapter 5. Finally, in the third section we define the Euler-Poincare characteristic for locally closed semi-algebraic sets.
