The “golden section” is when the ratio of the whole line (A) to the large segment (B) is the same as the ratio of the large segment (B) to the small segment (C); ie, A is to B as B is to C. Rockburne derives her rectangular golden sections from the square. The blue pencil lines follow the principles of dynamic symmetry.
