Penggunaan teorem Pythagoras
Hipotenus=a2+b2
a = hipotenuse2−b2
b=hipotenus2−a2

Contoh:
Rajah menunjukkan gabungan segi tiga bersudut tegak, PRS dan PQR.
PQ ialah hipotenus segi tiga kuning, PQ2=122+PR2
PR ialah hipotenus segi tiga biru, PR=32+42
PR=25=5cm
PQ2=122+52
PQ2=169
PQ=169=13cm
5
Contoh:
Rajah menunjukkan gabungan segi tiga bersudut tegak, QRS dan PQS.
SP ialah hipotenus segi tiga biru, 152=SQ2+PQ2
SQ ialah hipotenus segi tiga kuning,
SQ=62+82
SQ=100=10cm
PQ=152−102=225−100
PQ=125=11.18cm(2 t.p.)

Multiple Choice
Hitung nilai x dan nilai y. Pilih yang betul.
x=122+162
y =342+162
x = 122+162
y = 342−162
x=162−122
y = 342−162
x2=162−122
y2=342+162
7
Multiple Choice
Hitung nilai x dan nilai y
x = 10.58 cm
y = 37.58 cm
x = 20 cm
y = 30cm
x = 20 cm
y = 37.58 cm
x = 10.58 cm
y = 30cm
