Exercise 2-6
In this exercise we are going to draw some parallel
lines and measure angles. Do the following.
1. Place your ruler on a sheet of A4 paper in a
horizontal position.
2. Draw two lines above and below the straight
edges of your ruler 12 cm long. You now have
two parallel lines.
3. Rotate the ruler so it crosses the parallel lines
and draw two more as before. You now have
two sets of parallel lines crossing each other at
an angle you now going to measure.
