Your answer is either not a triangle or and isosceles triangle

I don't know which one is correct. But iI do know that it is one of those. Check out the link I sent you.
With 2 sides of length 9, you'd have a right triangle if the third side measured approx. 12.7
The third side is longer than 12.7, but it is less than 9 + 9 = 18.
That means you still have a triangle, but not a right triangle.
Since two sides are congruent, it is an isosceles triangle.
Seeing as @mathstudent55 has a higher smartscore, I would go with his answer. I'm better in English then math lol.
its c ok
@OM14forever You did a good job narrowing down the answer to only 2 choices.
One rule of triangles is that any side must always be shorter than the sum of the lengths of the other 2 sides.
Since 2 sides are 9 and 9, to have a triangle, the third side must be less than 18. Since 17 is less than 18, you do have a triangle.
