O estudo da fórmula de Brahmagupta para área de quadriláteros cíclicos

Abstract

Considering Geometry's notoriety and significant contributions to the field of science, this research emphasizes the work of Brahmagupta, a Hindu mathematician and astronomer known for his work in the geometric field, from the construction of a theorem used to calculate the area of cyclic quadrilaterals. Thus, the objective is to highlight and give prominence to the proposals for study and teaching from the work of this mathematician. To this end, we proceed to this context, foundations from theoretical and practical studies through demonstrations, followed by the application of the theorem, for that it was made use of mathematical concepts already known and an objective didactic language, in accordance with studies theorists of notorious research, among them Oliveira (2016). In this way, the relevance of Brahmagupta's work is observed, which allows us to better understand this very significant line of study and its contributions to teaching and plane geometry.
