Try to sort these graphs into families.

  • How will you choose to define the families?
  • Which features of the graphs will you use?
  • Are there some graphs which belong to more than one family?

Once you have sorted the graphs into families

  • Try to sketch a further example for each family.
  • Try to sketch a graph which would not belong to each family.

How else could you have sorted the graphs?
