I answered this over in the Chat Room where you posted it.

Remember this rule: The sum of the two smaller sides of a triangle must be greater than the third side. So which ones fail this rule? Looks like you have 2 answers that won't make triangles.

I remember a quick real world example for this rule. I think it was mentioned in this forum before.

Take three toothpicks, can you make a triangle out of them? (I should hope so)

Now take two toothpicks and a meter stick, can you get the two toothpicks to stretch ALL the way over to touch both ends of the meter stick, the answer is you can't. A side can't be bigger than the two other sides put together
