Answer:
(i) 3.2 cm
Step-by-step explanation:
When we add the length of two sides, it should be greater than the third side. If it is not greater than the third side, then triangle cannot be formed.
If you are taking the length of the third side as 3.2 cm,
3.2 + 2.5 = 5.7 < 6 cm
So, the length of the third side cannot be 3.2 cm
