    The main objective of this research is to determine in which measure the use of the GeoGebra tool affects the comprehension of the characteristics of the construction of Sierpinski's Triangle. The research matches a pre-experimental design within the quantitative explicative design, of applicative type; a non probabilistic sample of 40 8th grade students, taken from a populace of 123 students of the Instituto Técnico Industrial Pascual Bravo on Medellín on year 2016. For the use of GeoGebra, 9 sessions of 3 hours each took place and the data were gathered through a standardized test under the model based on evidences, a tool that allowed the recollection of the data before and after (pre and post test) the use of GeoGebra and was validated by 3 experts. The used method was the Kuder-Richarson 20 test, where the reliability of the tool (test), thrown the high value of 0,68401464. The Wilson statistic was used, which thrown the value of 19,5 for a signification of 0,05, concluding that the use of the GeoGebra intervention shows that it had a significant influence in the comprehension of the characteristics of Sierpinski's Triangle while comparing the group before and after its use. The results were significant for the comprehension of the characteristics of auto similarity (4,5), zero area and infinite perimeters of Sierpinski's Triangle (14,5), however for the fractal dimension characteristic it can't be concluded that it was significant, as seen in the test's results.
