GoGeometry Action 163!

Author:
Tim Brzezinski
Creation of this resource was inspired by a problem posted by Antonio Gutierrez (GoGeometry). What is the exact value of the ratio of the black segment (side of the larger equilateral triangle) to the purple segment (side of the smaller equilateral triangle)? How can we formally prove what is dynamically illustrated here?
