Números complexos aplicados à geometria

Abstract

This work aims to show some basic applications of complex numbers in plane Euclidean geometry. Here we seek to illustrate how you can work with complex numbers on geometric and also vector form, in order to present a more concrete way of teaching that content in the basic education. The versatility and applicability of complex numbers are presented in an accessible way to both teachers and students. Most of the geometrical demonstrations suggested are simple and can be easily worked with elementary education students, since geometrical concepts discussed are summarized to the content presented in schools during elementary school. We seek to establish, in several situations, comparisons between the algebraic and geometric, with the intention that students understand that these two areas, unlike most of them think, have different relations and can be easily studied together.
