In green, duplicate the left-most side below the right-most side
with one endpoint as that vertex:



In green, duplicate the left-most side again above the right-most side:



Connect the endpoints to the other two vertices



Duplicate those last two lines at the vertices:



What are the coordinates of those green vertices?
