We have to:
0. Draw 3 parallel lines.
,
1. Draw 2 transversal non-parallel lines
,
2. Mark the points of intersection between the transversal lines and the parallel lines.
We can start with the parallel lines:
We cann see that parallel lines never intersect.
Then, we draw two non-parallel transversal lines:
We will have 2*3 = 6 intersection points that we can mark:
