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.
