Question

b) Is it possible to have a triangle with the following sides?
6 cm, 7 cm, 9 cm​

Answer 1

Yes

It is possible

Because sum of the two smaller sides should be greater than the biggest side

6+7 = 13 > 9

Answer 2

Answer:

Yes triangle can be formed.

Step-by-step explanation:

triangle inequality theorem:

It states that the sum of any two sides of a triangle should greater than the 3rd side of the triangle .

let the sides of a triangle be a, b, c

then, a + b >c

b+ c > a

a + c > b

Here,

Given sides:

6 cm, 7cm,9cm.

according to the theorem:

6 + 7 > 9 = 13 >9

7 + 9 > 6 = 16 > 6

9 + 6 > 7 = 15 > 7

So, the triangle can be formed with 6 cm , 7cm , 9cm.
