DIVIDE A SEGMENT IN EQUAL PARTS USING THALES THEOREM

Some post ago an exercise was uploaded (see exercise) consisting of dividing a segment in equal parts. Here we are the steps that must be followed to get it done. 

THALES-EQUAL
STEPS:
First of all, we need to draw a segment and call it AB.
  1. From point A draw an oblique ray (r).
  2. Choose a measure with your compass and from point A translate that measure as many times as you want depending on the number parts you want to divide the segment into.
  3. Join the last point, in our case 7, with point B.
  4. Draw parallels to the segment B7 using your set square from the other points (1, 2, 3, 4, 5 and 6).
  5. Where those parallel lines cross segment AB we will get the points which divide segment AB in the desired parts.
