Teorema de Pick e teorema espacial tipo-Pick: demonstrações e aplicações no ensino médio

Abstract

Studies show that the performance of students in Mathematics is not satisfactory, since only a small portion of these students has the knowledge needed to pursue studies. The present work aims to create tools that can assist and improve classroom practices, more precisely in the studies of Geometry. We will present by counting Pick's Theorem, which calculates the area of a simple polygon by counting the points of the boundary and of the interior of the figure on a fixed lattice, making it a powerful tool of simple use for the understanding of the study of areas. Then we will present Reeve's Theorem that, similarly to Pick's, calculates the volume of a convex polyhedron by counting their lattice points, working on a secondary lattice of points Z3n, making a link between Geometry and counting.
