Daca ΔABC≈ΔDEF avem rapoartele de asemanare :
AB/DE=BC/EF=AC/DF
8/x=12/y=10/8
=>x=6,4
=>y=9,6
AB/DE=BC/EF=AC/DF
8/x=12/y=10/8
=>x=6,4
=>y=9,6
AC/DF=CB/FE=AB/DE
10/8=12/y=8/x
10/8=12/y=>y=(12×8)/10=>y=48/5
10/8=8/×=>×=(8×8)/10=>x=32/5
10/8=12/y=8/x
10/8=12/y=>y=(12×8)/10=>y=48/5
10/8=8/×=>×=(8×8)/10=>x=32/5
