a) xét tam giác ABC có :
BC=AC+AB (định lý Pytago )
BC= căn 45 +6
BC= căn 45 +căn 36
BC= căn 81
BC=9
b) xét tam giác ABC có ;
AC=BC+AB (Định lý Pytago )
AC=căn 24 +AB
7=căn 24+AB
Suy ra AB=7-căn 24
AB=căn 49-căn 24
AB=căn 25
AB=5
c) xét tam giác DEF có ;
EF=DF+DE(định lý Pytago)
căn 95=12+DE
Suy ra DE=căn 95-12
DE=căn 95-căn144
DE=căn-49
d)có tam giác PQR vuông cân tại Q (giả thiết)
Suy ra QP=QR(2 cạnh bên)
mà PQ=5cm(GT)
Suy ra QR=5cm
xét tam giác QPR vuông tại Q có;
PR=QP+QR(định lý Pytago)
PR=5+5=10cm
