The Golden Spiral is based on a pattern of squares and can be drawn
within a Golden Rectangle.
You will need:
- A4 squared or grid paper
- Pencil
- Ruler
What to do:
1. Begin by drawing a square with sides the same length as the
width of the paper.
2. Draw an arc from one corner of the square up or down until
it meets the joining or adjacent side:
3. Next draw another square joining the first. Draw an arc
across this square too.
4. Repeat the process to form the next square ... and so on.
What sizes are each of the squares that join onto each
other?
How do these growing squares connect with Leonardo
Fibonacci?
5. By drawing connecting arcs inside the sequence of squares, you
can construct the special curve known as the Golden Spiral:
