Abstract

The article presents a qualitative/descriptive research that aimed to analyze photographs obtained by researchers with regard to geometric shapes involved. For this, arguments were used in the analyzes based on visualization, imagination and creativity skills. The teaching of Geometry presents, according to authors, difficulties on the part of the teacher in associating theoretical foundations with real objects that are not always available in the school, academic or surrounding areas. The photographs analyzed focused on urban fences and railings in which the researcher's gaze quickly identified geometric elements that are usually used by definitions and the use of formulas, which leads to mechanical learning. The use of GeoGebra allowed a more accurate analysis of checking parallelism, perpendicularity, vectors, cartesian equations of certain elements as well as distinguishing, for example, between rhombuses and squares, arcs of concentric circles, tangent circles and others. We believe that the article can serve as a stimulus to teachers and their teaching in order to provide more meaningful learning, including developing geometric thinking and literacy.
