The work focuses on the study of triangles in elementary school, since the student has difficulties in understanding and interpreting flat figures and creating a relationship with problems. Hence, we searched for tools capable of awakening the student’s attention to geometry. We decided to use the software GeoGebra which is capable of reproducing the information described in a prob-lem on computer screens and similar, enabling more interactive lessons. Primarily an explanation of the content of plane geometry will be done, specifically about trian-gles, exploring concepts, properties and applications in the resolution of exercises. Next, we will make use of GeoGebra tools in order to address a meaningful way to build geometric knowledge, such as when you need to move a figure from one side to the other and make comparisons, then return to the same place, or even checking the sum of the internal angles of a triangle when mov-ing one of its vertices and noting the change in the values of each angle, but with a sum always equal to 180o. This work seeks to contribute to the evolution in the use of Information and Communication Technologies (ICTs) in education, making classes enjoyable for students who will have the oppor-tunity to experience innovative classes with technological attributes that facilitate learning
