Is it possible to construct a triangle with side lengths of 3, 6, and 9 units? If not, explain why not no; 9+6>3
O no: 6+39
no, 3+946
yes

no: 6+3 = 9

Step-by-step explanation:

In order to construct a triangle with given side lengths, sum of any two side length must be greater than the third side length.

Here we can see that:

6 + 3 = 9, which is defying the required condition.

Hence, it is not possible to construct a triangle with side lengths 3, 6, and 9 units.
