7. A second construction of the pentagram from a golden rectangle.

We start with the same golden rectangle as in the first method.

This time we swing EF about E until it meets BC being swung about B.

Extend EGC until it meets the circle centered at B again, and extend BG until it meets the circle centered at E again.

Call these points H and I. Find where the circle centered at H going through E meets the extension of HB, and find where the circle centered at I going through B meets the extension of EI

All we have to do to complete the pentagram is to extend EH and BI until they meet

 

 

We just have to connect our points to complete the pentagram.
