ÐK = 600
ÐM = 750
ÐL = 1800 - (600 + 750)
= 1800 - 1350
= 450
Jadi, besar sudut L = 450
Pada ∆ KLM
ÐD = 600
ÐE = 450
ÐF = 1800 - (600 + 450)
= 1800 - 1050
= 750
Jadi, besar sudut F = 750
Pada ∆ DEF

maka
ÐD = ÐK = 600
ÐE = ÐL = 450
ÐF = ÐM = 750
Karena sudut-sudut yang bersesuaian sama besar, maka ∆ DEF sebangun dengan ∆ KLM
