Answer 2

Answer:

the sum of two sides should be greater than the third side .

Step-by-step explanation:

1. 8.4 + 16.4 = 24.8 which is greater than 4.9

16.4 + 4.9 = 21.3 which is greater than 8.4

8.4 + 4.9 = 13.3 which is lesser then 16.4

so triangle cannot be formed in that case

2. 15+20 = 35 which is greater than 25

15 + 25 = 40 which is greater than 20

20 + 25 = 45 which is greater than 15

so triangle can be formed

3. 12 + 16 = 28 which is greater than 12

 12 + 12 = 24 which is greater than 16

12 + 16 = 28 which is greater than 12    

so triangle can be formed
