Álgebra geométrica do plano

Abstract

This work presents an introduction to Geometric Algebra building it on the plane from axioms. This approach allows for easy generalization to space and other dimensions. We believe that it can be introduced in high school and be successfully applied as a methodological alternative to teaching basic math concepts. This is a modern approach that reflects the current mathematical knowledge, unifying concepts involving geometry, trigonometry, systems of equations, complex numbers, and others which are usually presented in separation.
