This research is conceived while observing the loom knitting of the people living in the rural zone of Porcón, Cajamarca, in Perú, which provide evidence of artistic and geometrical abilities; then it is strengthen when comparing this innate geometric art with the poor results in mathematics as demonstrated by the tests applied World Wide (PISA), as well as those applied by the Ministry of Education in Peru (Measurement of Educational Quality, et al). Taking into consideration the design as extra-mathematical context, which may favor the creation of didactic models for the teaching of Geometry, our aim is to identify and classify the symmetries implicit in the design of that knitting, with a vision of its history and sociocultural description, placing emphasis on the educational dimension so as to value its art, and the no formal mathematical aspect by means of the contribution of Mathematical Education. The theoretical findings which support this study is the Ethnomathematics Theory by Ubiratan D’Ambrosio (1985). He points out that Ethnomathematics is the study of the mathematical techniques used by cultural groups identified to understand, explain and work out problems and activities which are born within their own environment. In the classification of the designs, we find that 85,7% use vertical symmetry by form(shape) and that 57,14% vertical symmetry by form(shape) and color. 14,28% of the designs consider symmetry respect a diagonal axis. The same way, in the friezes, one group equivalent to 44,44% presents only vertical symmetry; another 33,33% horizontal, central and vertical symmetry; one frieze only has horizontal symmetry with an 22,22 %. About students’ perception of symmetry, we find that they have a bilateral perception of the symmetry (vertical symmetric axis), 85,7% intuitively, based only on their visual capacity. It was observed that the students do not have a symmetry perception as regards a diagonal.
