Abstract:  We start with the definition of normal, very ample and smooth polytopes. We next define the projective toric variety X_A determined by a finite set A of lattice points. When A is the lattice points of a polytope P we demonstrate that X_A reflects the properties of P best if P is very ample. We also define the normal fan of P and discuss the relation betwen the corresponding "abstract" varieties X_P and X_A.
