Seth is using the figure shown below to prove the Pythagorean theorem using triangle similarity. In the given triangle DEF, angle D is 90° and segment DG is perpendicular to segment EF.

Part A: identify a pair of similar triangles. (2 points)

Part B: explain how you know the triangles from part A are similar. (4 points)

Part C: If EG=2 and EF=8, find the length of segment ED. Show your work. (4 points)
