Write brief answers to the following questions:
- Can you draw a triangle with this set of Logo commands? Discuss how or why not.
- Answer
- Logo only works with 90 degree angles and straight lines, so it is impossible to create a triangle that would require 45 degree angles. The only possibility would be to complete more of a zig zag on a very large scale to draft a triangle.
- Discuss: If you were designing the Logo language, how would you change some of our basic commands so that it would be easy to draw a triangle and easier to draw other shapes -- i.e., what should the basic commands do that would make drawing easier.
- Answer
- I would include the ability to skip particular blocks, to change angles by including a combination of forward and right, etc., and to vary the length of the lines from forward movement.
- What weaknesses do you find in using the procedures (the abstractions) we gave you -- forward, turn -- for drawing simple shapes? How would you change the definitions of these procedures to make it easier to draw shapes? Give a specific example that illustrates how a more powerful set of procedures would improve things.
- Answer
- The procedures are very general and do not take into account the repeated movements.
