## Find the missing parts of the diagram below

In the figure below, triangle ABC was reflected across segment DE onto triangle A'B'C', then the figure was rotated 100 degrees about point M onto triangle A''B''C''. Finally, the figure was translated along vector FG onto triangle A'''B'''C'''.
Given the above transformations, find segment DE (line of reflection), point M (center of rotation), and draw vector FG.
