In this article, we will focus on visualization solutions within specific geometric problem of the category Sangaku - historical mathematical problems from Japan. We also highlight didactical advantages of experimental activities in the teaching of mathematics and the role of the visualization via using dynamical geometry software GeoGebra.


Keywords –sangaku, GeoGebra, CAS environment, visualization, arithmetic sequence, Apollonius’ net.
