The objective of this research work was to analyze how high school fourth grade students mobilize the concept of the similarity of triangles through different semiotic representations. It was carried out with fourth-grade students of secondary education from a private educational institution in Lima whose ages ranged from 14 to 15 years. The problem that gave rise to this study was based on the difficulty that students have in mobilizing the concept of similarity of triangles in solving problems, a difficulty generated by teaching through the direct use of the similarity ratio, without time suitable to develop it in class and without the use of some software that facilitates the approach of the problems. Aspects of Didactic Engineering were used as a methodology and the Theory of Registers of Semiotic Representation as a theoretical reference, emphasizing the figural register, in its various apprehensions. Regarding the experimental part of the research, a sequence of three activities was carried out with the intention that students mobilize the concept of similarity of triangles in solving problems of everyday life using both pencil and paper and GeoGebra. In the first activity two problems with figural registration and supported by GeoGebra were addressed, in the second activity a problem was proposed without figural registration but supported by GeoGebra and the third activity raised a problem without figural registration and without GeoGebra support. Likewise, the changes in the register of semiotic representation were identified, as well as the perceptual, sequential, operative and discursive apprehension that the students mobilized in the sequence of activities and it was concluded that the fourth-grade students of secondary school managed to mobilize the concept of similarity of triangles by medium of different semiotic representations and GeoGebra.
