Ac=AB+BC
AC=5 cm +0,5cm
AC= 5,5cm

AD= AB +BC+ CD
AD= 5 cm+0,5cm+ 1,5 cm
AD= 7cm

AE=AB+BC+CD+ DE
AE= 5cm +0,5cm+ 1,5cm+ 7cm
AE= 14cm

BD= BC+CD
BD= 0,5cm + 1,5 cm
BD=2 cm

BE= BC+CD+DE
BE= 0,5cm+ 1,5cm+ 7 cm
BE= 9cm

CE= CD+ DE
CE= 1,5 cm+ 7cm
CE= 8,5cm

2.Ac+CE-AE= 5,5cm + 8,5cm-14cm= 14cm -14cm= 0cm
AB-BA= 5cm-5cm= 0cm
AB si BA sunt aceleasi segmente.

3. AE: AD= 14cm: 7cm= 2 (a doua parte)
AE:AB= 14cm: 5cm= 2,8
