  • The animation presents, on its initial screen, a beam formed by three parallel lines, two lines cross to this beam, three corresponding points of two transversal and two corresponding segments. On the right of the screen the value of the measurements of the line segments are set, their respective corresponding segments and the relation of equality between the reasons of segments formed by the line which is transversal to the beam. The learning object allows moving the lines of the beam and the transverse around the screen, allowing to verify Tales’ theorem through several measure values
  • To have primitive notions of geometry, such as point, line and plane
