Verified answer
D = H ( sehadap )G + H = 180 ..(1) , sudut lurus
G = 4D
G = 4H ( karena H = D)..(2) subsitusikan (2) ke (1), maka 4H + H = 180
5H = 180
H = 36°
G = 4.36
G = 144°
A = G = 144° ( luar berseberangan)
B = D = H = 36 ( bertolak belakang )
C = G = 144 ° ( sehadap)
D = H = 36 (sehadap )
E = G = 144° ( bertolak belakang )
F = H = 36 (bertolak belakang )
