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.
Part B: Explain how you know the triangles from Part A are similar.
Part C: If EG = 2 and EF = 8, find the length of segment ED. Show your work.
