Resumo: The objective of this article is to present the investigation realizedabout the knowledge of high school students on defining attributes of theconcept of polygon. The participatings of the study were 253 students of highschool, who answered a test of defining attributes, and six of them were selectedfor individual interviews, kind of semi-conducted, that they were audio-recordedand transcripted for analysis. The results showed that the general average (M =6,0), in the test of defining attributes, was low and that the statistic test pointedout the significative differences (p < 0,05) in the percentages of rights in fouraffirmations from the 14 which were analysed. However the test did not presentsignificative differences among the average of each series. The analysis alsoshowed that the interviewed people had difficulties to identify three definingattributes of polygons: flat figure, straight line segments and simple figure.

Os participantes do estudo foram 253 alunos do Ensino Médio, que responderam um teste de atributos definidores, sendo que seis deles foram selecionados para entrevistas individuais, do tipo semi-dirigida, as quais foram audiogravadas e transcritas para anáise. Os resultados mostraram que a média geral (M = 6,0), no teste de atributos definidores, foi baixa, e o teste estatático apontou diferenças significativas (p < 0,05) nas porcentagens de acertos em quatro afirmações, das 14 que foram analisadas. Porém, o teste não apresentou diferenças significativas entre as médias de cada série. A análise também mostrou que os entrevistados tiveram dificuldades em identificar três atributos definidores de polígonos: figura plana, segmentos de reta e figura simples.Universidade Estadual de Campinas2009-12-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionTextoinfo:eu-repo/semantics/otherapplication/pdfhttps://periodicos.sbu.unicamp.br/ojs/index.php/zetetike/article/view/864672310.20396/zet.v17i31.8646723Zetetike; Vol. 17 No. 1 (2009): jan./jun.
