Pembuktian Teorema Pythagoras
F
Dari gambar di samping, dapat dilihat bahwa
segiempat ABHI , JHBC , ADGC dan EDGF
E
adalah konruen (S,S,S). maka:

G
B

Luas (ADGC)+luas (EDGF)

= luas (ABHI) + luas (JHBC)

Luas (ADEFGC)

= luas (ABCJHI)

Karena, bangun ADEFGC dan bangun ABCJHI memuat 2
segitiga yang kongruen dengan sigitiga ABC, maka:

Luas (ADGC)+luas (EDGF)

C

I

J

= luas (ABCJHI)-2.luas(ABC)

Luas (ABED)+luas (BCGF)

A

= luas (ABHI) + luas (JHBC)

Luas (ADEFGC)-2.luas(ABC)

D

= luas (ACHI)

H
