I'm confused on triangles

If you try to construct it you will understand why what CPhill is telling you is so.  

The 2 short sides will not be long enough to touch each other.

Oh dear, that would be a three intervals that can't 'hold hands'  not much of a tirangle I am afraid.    

it depends on what type of triangle you are trying to figure out is it a right triangle or what

If the triangle is "right-angle" triangle the answer is "No". If it is NOT right-angle triangle, then the answer is "Yes".

Just try to construct the triangle, the question answers itself.

That is a good answer last guest :))

YES try constructing it.  Start wit the longest side and then try to get a triangle using the two short lengths.

See what happens.     

NO!!!!!.....this violates the triangle inequality which says that the sum of any two sides of a triangle is greater than the remaining side.

But  :

6 + 2  < 9.3

So....this triangle is impossible.....
