Of native mathematics in the thinking of the traditional authorities of the Tribu Umbundo with respect to the form of Ondjango in Cuito / Bié-Angola for isoperimetric problems of flat geometry

Abstract

This article presents an approach related to the thawing of native and intuitive mathematics frozen in the thinking of the traditional authorities of the municipality of Cuito whose mathematical interpretation process suggests a motivational and significant activity in the teaching-learning of flat geometry, based on the student's context. The mathematical result presented allows a cultural decolinization leading to a possible understanding on the part of the student that Mathematics is not something completely foreign imported from outside Africa. The mathematical ideas extracted from an informal conversation with the traditional authorities of the municipality of Cuito can contribute to the optimization of the Teaching-Learning Process in the subject of Flat Geometry.
