Sudut C = 180 - 150 = 30
Sudut A2 = 180 - 50 - 30 = 100 (sudut segitiga)
Sudut A1 = sudut B = 50 (sudut dalam berseberangan)
Sudut A3 = sudut C = 30 (sudut dalam berseberangan)
sudut A₁ = 50
sudut A₃ = 180 - 150 (sudut dalam sepihak)
sudut A₃ = 30
sudut A₂ = 180 - (50 + 30)
sudut A₂ = 180 - 80
sudut A₂ = 100
