The construction of figured numbers in GeoGebra software using algebraic properties

Figured numbers are sequences of natural that, when represented by dots, form geometric configurations. The immediate sequence figured presents in its configuration the equilateral triangles, being basis for finding several others, as long a relationship between them is discovered. This article shows construction polygonal, stellar and three-dimensional that can be constructed using GeoGebra software resource to visualize properties relate these triangular numbers. It way observing figures shown have each other, how we understand structure sequences, presented figures, possibility building represent some most known within number’s such 2D square, pentagonal, centered star 3D Thus, this work through pyramidal numbers, cubic octahedral two forms stella octangula with emphasis on use or other depart from one. Furthermore, constructing well discovery possible them.
