Question

Can the following side lengths form a triangle? Explain. 6, 9, 12​

Answer 1

For a triangle to form sum of any 2 sides must be greater than 3rd side and it should staify in all 3 pairs.

So let sides be a= 6 ,b = 9 , c =12

6+9>12

6+12>9

12+9>6

so all 3 satisy therefore it can form an triangle
