Explicație pas cu pas:
a) AD²= BD*DC= 3*27= 81
AD= 9 cm
BC= BD+DC= 3+27=30 cm
b) AD²= BD*DC= 18*8= 144 => AD=12 cm
DC= BC-BD= 8 cm
c) AD²= BD*DC => BD= 576/48 = 12 cm
BC= BD+DC= 60 cm
d) AD²=BD*DC => DC= 225/9=25 cm
BC= DC+BD= 34 cm
e) AD²= 4[tex]\sqrt{2} [/tex]*2[tex]\sqrt{2} [/tex]= 16 => AD= 4 cm
BC= DC+BD= 6[tex]\sqrt{2} [/tex]
f) AD²=BD*DC => BD= 23.04/6.4= 3.6 cm
BC= BD+DC= 10 cm
