Geogebra - There and Back!

In this activity we will walk from Federation Square to Parliament.  You can only use the main streets of the CBD.

  1. Load this Geogebra file

You should see this polyline.

  1. Now move point H to position (4,2)

The move must leave the polyline remain at a = 10.

  1. Now move any of the points C to K.
  2. You may only move the point one integer coordinate at a time.
  3. You may not cross over or go back!
  4. Each time you move these points the polyline value must remain a = 10.
 

 

Questions
  1. If you walk from Melbourne Central to Parliament, what is the distance?
  2. What is the distance if you return to Melbourne Central?
  3. Explain why a return path of this shape would always have length of 20.
  4. What type of walk would you make if you broke the rule a = 10 ?
Activities
  1. Use the "Interval between two points" to draw a straight line from Melbourne Central to Parliament.
  2. Save a copy of your new polyline walk in your "Maths is Amazing" folder.
