By parallel lines, we will have ∠ ABC = ∠ DFE = 80° and ∠ BAC = FDC = 80°. We also have ∠ C = 20°. Step 2: Prove FD = FE This step is quite hard. Construct AF and label its intersection with BD as G. Consider triangle BDF. We are given ∠ DBF = 20°. Then ∠ BFD = 180° – ∠ DFC = 180° – 80° = 100°. hemodialysis kidney disease
