To create a rectangle with this golden ratio:

1. Draw a square.

   

2. Extend two parallel sides.

   

3. Draw a line from the midpoint of one side of the square to the opposite corner.

   

4. Using the line you just drew as a radius, draw an arc between the twoparallel lines.

   

5. Draw a perpendicular line from between the parallel lines from the intersection of the arc on the bottom line.

   

6. You now have a golden rectangle.
