O presente artigo traz para discussao a desconstrucao dimensional das formas como elemento relevante a se considerar na aprendizagem da geometria. A investigacao baseou-se em aportes teoricos de Duval que traz a desconstrucao dimensional das formas como intrinseca a aprendizagem em geometria. A pesquisa teorica/pratica baseada em principios da Engenharia Didatica faz uma analise semiotica e cognitiva das producoes de alunos do Ensino Medio em problemas que contenham figuras geometricas. A desconstrucao dimensional das formas mostrou-se ser uma operacao cognitiva requerida e fundamental a resolucao de problemas com figuras se configurando no momento seguinte as apreensoes perceptiva e discursiva e agindo no planejamento heuristico da acao do sujeito que o encaminhando para um olhar nao iconico que decompoe os elementos constitutivos da figura, permitindo a solucao do problema. O presente estudo nos direciona a necessidade do olhar docente a proposicao de problemas com intencionalmente para o desenvolvimento da desconstrucao geometrica favorecendo as operacoes na figura em suas dimensoes inferiores. The present article brings to discussion the dimensional deconstruction of forms as a relevant element to be considered in the learning of geometry. The research was based on Duval's theoretical contributions which brings the dimensional deconstruction of forms as intrinsic to learning in geometry.Theoretical / practical's research based on Didactic Engineering principles makes a semiotic and cognitive analysis of the productions of high school students in problems that contain geometric figures.The dimensional deconstruction of the forms has been proved to be a required cognitive operation and fundamental  to solve problems with figures settling in the moment following the perceptive and discursive apprehensions and acting in the heuristic planning of the action of the subject that leads it to a non iconic view that decomposes the constituent elements of the figure, allowing the solution of the problem.The present study directs us to the necessity of the teaching view to the proposition of problems with intentionally for the development of the geometric deconstruction favoring the operations in the figure in its inferior dimensions .
