The Attempt at a Solution

8.2.1)
Let D₁ = x
D₄=D₁
=x
D₄=L₁ (tan chord theorem)
L₁=x

D₁=L₂
L₂=x

angle KLM=2x
KNM=2x(opp angles in //gram)
ENF=2x(vert. opp angles)
EDF=180-2x(supp. angles)

therefore DENF is cyclic quad, opp supp angles ENF and EDF.

8.2.2

E₂=x(tan chord theorem)
G₁=90 (KM//HJ)

I need help trying to prove E₂ is = to G₁
