The structure plan in this example defines a geometric construction. Carry out the plan by sketching the construction:
1. Draw two perpendicular x- and y-axes
2. Draw the points A (10, 0) and B (0, 1)
3. While A does not coincide with the origin repeat: Draw a straight line joining A and B Move A one unit to the left along the x-axis Move B one unit up on the y-axis
4. Stop.
