Task 1


Choose one pattern of an airplane or an origami object you would like to fold. Completely fold your airplane or object, then unfold the paper back to a flat, single sheet of paper.

Task 2


Refer to your unfolded paper to answer the following questions.

  1. How many fold lines did you create?

  2. How many angles were created from folding the paper?

  3. Do you see any parallel lines?

  4. Do you see any perpendicular lines?

  5. Can you identify angles that might be equal in size? If so, how could you be sure if they are equal in size?

   Points to Ponder

For an airplane, if you tried a different folding pattern with different angles, would the plane fly better? How do different angles affect the wind resistance and the manoeuverability of a plane?
