Answer:

3 cm, 4cm, 5cm.

Step-by-step explanation:

a) 2cm, 2cm, 5cm.

(2+2)cm= 4cm<5cm

(2+5)cm= 7cm>2cm

(5+2)cm= 7cm>2cm

It can't be a triangle as in the first case the sum of two sides is less than the third side.

b) 3cm, 4cm, 5cm.

(3+4)cm= 7cm>5cm

(4+5)cm= 9cm>3cm

(5+3)cm= 8cm>4cm

It can be a triangle as in all the cases the sum of two sides are greater than the third side.
