... ∠ECD = x = ∠EGF. An exterior angle of a triangle has a measure equal to the sum of the remote interior angles, so ∠AFG = 2x = ∠BDC. Since 4AFG and 4BDC are isosceles, ∠FAG = 2x = ∠DBC. ∠ACB and ∠BGA are exterior angles of 4ECB and 4EGA, respectively, so they each have measure x + 2x = 3x. But 4ABC a ...
